About this lesson
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.
