Geometry on Khan Academy: We are surrounded by space. 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. We've also partnered with institutions like NASA, The Museum of Modern Art, The California Academy of Sciences, and MIT to offer specialized content.

This is the first lesson in the triangles series of Tristan's Learning Hub. In this lesson, you will be introduced to five common types of triangles: Isosceles, Equilateral, Right-angled, Scalene, and Right-angled Isosceles.
The creator is 12-year-old Tristan Pang who is studying university level maths. He has taught himself all the high school maths curriculum before the age of 5. He learnt vertically, topic by topic without taking any notice of the year levels.The objective of his website is to share his way of learning. In his videos, he won't tell you the year level of each episode. And by the last episode of each topic, you will know you have already reached the year 13 level.

Our Mission: MashUp Math is our creative solution to reviving students' passion and interest for learning mathematics. As young educators, we know that all students learn math differently and that a one-size-fits-all approach is simply ineffective. The idea that the ability to understand mathematics is reserved for a select few did not sit well with us.
In addition to sharing free teacher resources (which are teacher created resources) in the form of teacher worksheets, we share new YouTube math videos every week that help math teachers and students to better understand mathematics and the common core. Our lessons can be aligned with the common core standards for common core math and are immensely popular with flipped learning educators and anyone experimenting with flipped classroom learning.
As educators, we know what it takes to be a super math teacher and that we can’t always do it alone. In addition to our cool math videos, we share articles, blogs, inspirational quotes, teacher math worksheets, and math worksheets. Whether you teach in the flipped classroom, operate in blended education or online blended learning, or are interested in finding cool math online, MashUp Math will have something for you!
Many students think of us as a math tutor online or as their on-demand online tutor. Others trust us for all things related to online math education—coming to use when they find themselves thinking “I don’t understand my homework assignment! and need some homework help!
It is also a part of our mission to make progressive steps in mathematics education. For one, our content is created with the goal of moving students from a fixed mindset to a growth mindset. We also aim to meet the unique needs of ESL math students and support math for girls as well.
Many of our users serve as a special education teacher and use our cool videos to support their special education students with special needs. Our free online math lessons are also high adaptable to your homeschool curriculum and should be added to your list of free homeschool resources.
We are also very involved in the edtech world and are very popular with Google Classroom educators, Math Games Classroom Educators, and teachers who support the use of iPad for education!
So if you could use some help with everyday math and are a student with a unique learning style or learning styles—like Visual Auditory Learning! Or if you’re tired of math games and are more interested in an easy-to-follow tutorial, check us out and learn math with us. No matter your school’s standards of learning, our YouTube Math Videos Lessons will work for you!

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.

How to use angle side angle to prove that two triangles are congruent.
The video gives step by step directions on how to prove that triangle ABC is congruent to triangle CDA.
When you prove two triangles are congruent using the angle side angle you must prove that an angle,an included side, and another angle are all congruent. In this proof alternate interior angles, and the reflexive property are used to prove the two triangles are congruent.

Properties of similar triangles
Triangles are similar if they have the same shape,but not necessarily the same size.
Properties of similar triangles
The corresponding angles are the same
The corresponding sides are in proportion
We can prove triangles are similar by:
Angle Angle ( two angles congruent to two angles of another triangle)
Side Side Side ( ll three sides in proportion to all three sides of another vtriangle)
Side Angle Side ( two proportional sides with congruent angle in between)
The video "Similar Properties" reviews these properties and provides examles.

The vertex angle of an isosceles triangle is the non congruent angle and is opposite the base
The video describes the vertex angle and works two sample problems
What are the measure of the base angles given a vertex angle of 110 degrees?
What is the measure of the vertex angle given a base angle of 70 degrees?

What is a scalene triangle?
Transcript
Scalene Triangles
Welcome to MooMooMath. Today we are talking about Scalene Triangles. A scalene triangle is one in which all three angles are different. So let's look at two examples. I'm going to mark these triangles 3 inches, 4 inches, and 5 inches. All three sides are different lengths. This triangle over here is marked such that all three sides are the same. The mark on the side represents equal lengths. This is actually an equilateral triangle. Now let's look at a scalene triangle based on angles. You have a forty five degree angle, a forty five degree angle, and a ninety degree angle, and over here you have a 60 degree angle, a 30 degree angle, and a ninety degree angle. So based on angles which of these is a scalene angle? This one here (circles the triangle with 60, 30, 90 degree angles) because all three angles are different or all three sides are different. The other triangle these two angles are the same meaning these two legs are the same so this one is actually what they call an isosceles triangle. So let's look at the rules. The definition is all sides are different lengths and all angles are different measures. So our 3, 4, 5, is our example. Hope this video was helpful.
