This three-minute video is from Sal Khan about using the Pythagorean Theorem to solve a word problem: A carpet measures 7 feet long and has a diagonal measurement of square root of 74 feet. Find the width of the carpet Mr. Khan uses computer software for demonstration. The screen is a little 'busy' so the viewer may want to open the screen to 'full screen' to see all more clearly.

45-45-90 triangles | Right triangles and trigonometry | Geometry | Khan Academy
By Khan Academy
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.
