Introducing Pythagoras's Theorem

This introduction of Pythagoras’s Theorem includes two proofs. The first proof is suitable for lower ability students, the second for higher ability students. I have also included an investigation that give you an oppertunity to show your students how this important theorem can be applied within the school. The investigation canb be made in to a practicle one if you wish.
I have also included a small exercise with answers, that will allow the reinforcement of your initial introduction of this theorem.

The second proof requires a good level of algebra for a full understanding. I recommend you use this proof after covering expanding brackets and factorising in algebra.

I also like to mention to my students although this theorem is now known as Pythagoras’s Theorem who lived about 500 BC, he was not the first to have discovered it. It was known by the Babylonians and the Eygptians.
