Video uses an electronic black board with different colored pens. Introduction to 45-45-90 Triangles, these can also be called right triangles because of the 90 degree measurement. These triangles are special because if two angles of a triangle are... equal the one side they don’t share is going to be equal. This then goes on to explain Pythagorean Theorem, Side A squared + Side B squared = Side C squared, side C is the hypotenuse or the side that is shared in a triangle. The narrator goes on to explain how to solve, using square roots. This video is for middle school students. (09:30)

Video uses an electronic black board with different colored pens. Narrator reviews a 45-45-90 triangle and how to solve for the hypotenuse using the Pythagorean Theorem. Then narrator goes on to a 30-60-90 triangle, where one angle is 30 degrees, a...nother angle is 60 degrees and the last angle is 90 degrees. The length of the sides is the discussed and found. This video is for middle school students. (09:40)
