Khan Academy Video Review

This video was helpful because it revealed a new method in finding out a side. In class for the shorter leg it was always core variable meaning say x was the shorter leg and the hypotenuse was x times 2, but in this it was the hypotenuse divided by two  which equals the shorter leg. Also in class we were taught it was the shorter leg time the square root of three, but in the video it was the square root of 3 divided by 2 and times the hypotenuse. It was a new method and seemed easier than what was taught in the classroom
