This is the first video in the Year 9 series looking at Pythagoras' Theorem and right angled triangles. This video is really an introduction to who Pythagoras was and the formula he (probably didn't) come up with. I look at some basic examples of using the formula and how you might want to do it another way! The theory is explained in an easy to understand way.

There are no current errors with this video ... phew!
