## Pythagoras' Theorem |

- This is with good reason the most famous theorem in all of Mathematics!

There are many ways of proving this important theorem and no-one's education can be said to be complete without understanding at least one.

Here are some links to proofs of the theorem that you can find on the
Web:

This award winning presentation of an animated proof of Pythagoras' Theorem by UBC's Jim Morrey was an early example of the use of JAVA to help with the understanding of mathematical ideas.Here's another presentation of the same proof (by the IES group in Japan)

(This latter site also illustrates a number of other proofs of the theorem, and allows you to see how some apparently different arguments are really just different aspects of the same basic principle.)
