And that space contains lots of things. And these things have shapes. In geometry we are concerned with the nature of these shapes, how we define them, and what they teach us about the world at large--from math to architecture to biology to astronomy (and everything in between). Learning geometry is about more than just taking your medicine ("It's good for you!"), it's at the core of everything that exists--including you. Having said all that, some of the specific topics we'll cover include angles, intersecting lines, right triangles, perimeter, area, volume, circles, triangles, quadrilaterals, analytic geometry, and geometric constructions. Wow. That's a lot. To summarize: it's difficult to imagine any area of math that is more widely used than geometry. About Khan Academy: Khan Academy offers practice exercises, instructional videos, and a personalized learning dashboard that empower learners to study at their own pace in and outside of the classroom. We tackle math, science, computer programming, history, art history, economics, and more. Our math missions guide learners from kindergarten to calculus using state-of-the-art, adaptive technology that identifies strengths and learning gaps.

Translations Reflections and Rotations
 
09:12
Transformation means movement of objects in the coordinate plane. Transformation can be done in a number of ways, including reflection, rotation, and translation. Reflection is flipping an object across a line without changing its size or shape. Rotation is rotating an object about a fixed point without changing its size or shape. Translation is sliding a figure in any direction without changing its size, shape or orientation.

For a complete lesson on proving triangles are congruent, go to http://www.MathHelp.com - 1000+ online math lessons featuring a personal math teacher inside every lesson! In this lesson, students learn the following postulates related to congruent triangles and triangle proofs. If the three sides of one triangle are congruent to the three sides of another triangle, then the triangles are congruent (Side-Side-Side or SSS). If two sides and the included angle of one triangle are congruent to two sides and the included angle of another triangle, then the triangles are congruent (Side-Angle-Side or SAS). If two angles and the included side of one triangle are congruent to two angles and the included side of another triangle, then the triangles are congruent (Angle-Side-Angle or ASA). Students are then asked to determine whether given triangles are congruent, and name the postulate that is used.

We make animated math videos and educational songs for kids that bring joy back into math class and make it cool again! Up until today, we have created nearly 30 animated music videos that cover mathematical concepts for 3rd Grade, 4th Grade, and 5th Grade; concepts like, Rounding Numbers, Ordering Decimals, Subtraction, 3D Shapes, Types of Angles and much more! We're curious to see how our teaching resource will be used now that we have shared them with a broader audience. Thanks for your interest. How did NUMBEROCK begin? When you look at the entertainment that’s being produced for kids in games and movies, it’s no wonder that kids are starting to zone out in school. During the last 7 years as an elementary public school teacher, I’ve always tried to find new ways to capture my students’ full attention, especially for that one subject that gets such a notoriously bad rap in elementary school – math. One day I brought my guitar in to school to play a song I’d written about Long Division that was accompanied by some simple animations I’d made. While not all my students liked the folk rock genre, I could tell I had everyone’s attention. Soon I began writing songs in genres that my students actually listened to: rap, rock, pop, country, you name it. Parents would tell me that their kids were singing the songs in the car, at dinner, even teaching them to their siblings. Almost in disbelief that kids were singing my math songs for fun outside of school, I felt encouraged and inspired to keep writing. Then, three years ago, I had one of those ‘AHA!’ moments: to write a song with a simple animation for every math concept I had to teach. Altogether, from 2008 to now, I’ve written songs for nearly 50 concepts, 30 of which are now professionally animated. Lesson materials to help maximize learning for those 30 songs are available at "Teachers Pay Teachers", a website where teachers, homeschoolers, and parents can buy high quality learning materials. I hope your student(s) will find a renewed passion for math as they access the NUMBEROCK method.

What are special right triangles?

Geometry Teachers Never Spend Time Trying to Find Materials for Your Lessons Again! Join Our Geometry Teacher Community Today! http://geometrycoach.com/Geometry-Lesson-Plans/?pa=MOOMOOMATH http://www.moomoomath.com/Special-Right-triangles.html Special right triangles are triangles that have regular patterns that makes calculations of the triangle easier. Two common special right triangles, are the 30-60-90 triangle and the 45-45-90 triangle Transcript Special Right Triangles Hi welcome to MooMooMath. Today we are going to look at two type's special right triangles. The first type is 30-60=90 triangles and the second type is the 45-45-90 type triangle. Something special about the 30-60-90 triangle is that all three angles are different therefore all three sides are different, so this triangle is scalene because all three sides are different. So let's draw a 30-60=90 triangle. So if this is my triangle the smallest is this 30 degree angle and this other acute angle would be my 60 degree angle and of course my right angle would be my 90 degree angle. Now opposite my smallest angle is the shortest leg, the longer leg is opposite 60 degree angle and the right angle is always opposite the hypotenuse. So that's how you would label it. So go ahead and label the short, long leg, and the hypotenuse. Now on a 45-45-90 notice you have two angles that are congruent, therefore we have an isosceles triangle which is a triangle with two sides that are the same length and these two angles are my 45 degree angles. So this angle is 45 and this angle is 45. Since these two angles are congruent the legs will be congruent. So these are my two legs. Leg 1 and leg 2 and this is my hypotenuse because it is opposite the 90 degree angle and it is the longest side in a right triangle. So I hope this video of right triangle was helpful, we have two other videos, one which focuses on solving for 30-60-90 triangle and another that solves for 45-45-90 degree triangles. .For a summary of the video and a practice link go to http://moomoomath.com You may also enjoy… Special right triangles in Geometry 30-60-90 45-45-90 https://www.youtube.com/watch?v=nVTtSE5nv7c Special Right Triangle Explanation https://www.youtube.com/watch?v=nVTtSE5nv7c Special right triangles https://www.youtube.com/watch?v=nVTtSE5nv7c -~-~~-~~~-~~-~- Please watch: "Study Skills Teacher's Secret Guide to your Best Grades" https://www.youtube.com/watch?v=f3bsg8gaSbw -~-~~-~~~-~~-~-

And that space contains lots of things. And these things have shapes. In geometry we are concerned with the nature of these shapes, how we define them, and what they teach us about the world at large--from math to architecture to biology to astronomy (and everything in between). Learning geometry is about more than just taking your medicine ("It's good for you!"), it's at the core of everything that exists--including you. Having said all that, some of the specific topics we'll cover include angles, intersecting lines, right triangles, perimeter, area, volume, circles, triangles, quadrilaterals, analytic geometry, and geometric constructions. Wow. That's a lot. To summarize: it's difficult to imagine any area of math that is more widely used than geometry. About Khan Academy: Khan Academy offers practice exercises, instructional videos, and a personalized learning dashboard that empower learners to study at their own pace in and outside of the classroom. We tackle math, science, computer programming, history, art history, economics, and more. Our math missions guide learners from kindergarten to calculus using state-of-the-art, adaptive technology that identifies strengths and learning gaps.

Properties of an equilateral triangle-Geometry Help-MooMooMath

Geometry Teachers Never Spend Time Trying to Find Materials for Your Lessons Again! Join Our Geometry Teacher Community Today! http://geometrycoach.com/Geometry-Lesson-Plans/?pa=MOOMOOMATH http://moomoomath.com http://www.moomoomath.com/Equilateral-Triangle.html Hi Welcome to MooMooMath. Today we are going to look at Equilateral Triangles. Up here I have two different triangles. The first one we know is equilateral because all three sides are marked congruent. You might see a congruent symbol like that (points to triangle) or you might see that the measure of each side is equal. So there is two ways to show that the different sides are equal. On the second one let's look at it in perspective of the actual measure of the angles. We know that a triangle adds up to 180 degrees. So if we have three equal angles we are going to take that and divide it by three. So 180 divided by three is equal to 60. That means each of these angles have to measure 60 degrees. If the three angles measure 60 then it is an equilateral triangle. So let's look at the rules. The first rule is that all three sides of the triangle are congruent which just means they are equal, and all three angles have to be congruent, which are equal measures. In an equilateral triangle since you have triangle and it always adds to 180 the measure of the angles will always be 60. Hope this video was helpful. -~-~~-~~~-~~-~- Please watch: "Study Skills Teacher's Secret Guide to your Best Grades" https://www.youtube.com/watch?v=f3bsg8gaSbw -~-~~-~~~-~~-~- Review Geometry terms with this crossword puzzle http://www.moomoomath.com/geometry-terms-crossword-puzzle-answers.html

Geometry Teachers Never Spend Time Trying to Find Materials for Your Lessons Again! Join Our Geometry Teacher Community Today! http://geometrycoach.com/Geometry-Lesson-Plans/?pa=MOOMOOMATH Properties of a rhombus,rectangle, and a square A rhombus,rectangle, and square are all polygons. In addition each of these are quadrilaterals, which mean they have 4 sides. A rhombus is a quadrilateral with 4 equal sides. A rhombus is most commonly recognized as a diamond, but they are not limited to this shape. Let's take a look at 14 properties of a rhombus. A Rhombus is a Quadrilateral, which means it has four sides, and the sides of a rhombus are congruent. The opposite sides of a rhombus are parallel. The opposite angles of a Rhombus are congruent. The diagonals of a rhombus are perpendicular. The diagonals of a Rhombus create form four congruent interior triangles. The diagonals of a rhombus bisect each other which means they cut each other in half. A rectangle has opposite sides that are congruent. in addition a rectangle has 4 right angles, and diagonals that are equal. A rectangle is part of the quadrilateral family. A rectangle is a plane shape with 4 sides. In addition, it has several other properties A rectangle is a 4 sided polygon, with opposite sides being parallel. In addition, a rectangle has 4 right angles and the sum of the interior angles add to 360 degrees. The diagonals of a rectangle are equal length The diagonals bisect and create two equal triangles. Opposite sides are equal and parallel All squares are rectangles, but not all rectangles are squares. A square is also a quadrilateral with four equal sides plus four right angles. The diagonals of a square bisect one another, plus bisect opposite angles which creates two angles of 45 degrees. A square is a plane shape that is a quadrilateral that is 2D so it has length and width but not height. A square has 4 congruent sides 4 equal sides. Along with these 4 sides a square has 4 right angles The diagonals are perpendicular and create 4 right angles. The diagonals bisect each other. The diagonals of a square also bisect opposite angles and create equal 45 degree angles. The diagonals create congruent triangles Triangle ABC is congruent to ACD A square can be considered a rhombus with four right angles or a square with 4 equal sides.

Teacher Toolkit: Triangle Circle Square (Secondary)
 
02:11
http://www.theteachertoolkit.com/ See Leticia Garza, middle school math teacher, using Triangle Square Circle to assess her students' learning at the end of class. This strategy encourages students to reflect on their learning and process information presented in the lesson. Similar to other closing strategies, it asks students to pick out important pieces of information and to question anything they don’t completely understand. As a teacher, it is a tool that will be used to gauge understanding and determine if anything needs to be re-addressed in future lessons. Find more tips and videos at: www.theteachertoolkit.com
