How do I use Pythagoras to work out the length of a triangle?

Pythagoras is a theory that works for right-angled triangles and allows us to work out the length of its sides.The theory is: x2 = a2 + b2 (I will show this with a diagram)I will then walk the student through an easy example question using the whiteboard.Lastly I will walk the student through an example question from a past paper using the whiteboard.
