Description
This is another video in the Pythagoras' Theorem series of video which looks at how to use his theorem to find the length of the shorter sides of a right angled triangle. We know the longest side (normally called c) of a right angled triangle is called the hypotenuse. The other two sides (a and b) can be found if we know the length of two other sides using Pythagoras' Theorem. In this video I show lots of worked examples all explained in an easy to understand way.
