The_Pythagorean_theorem

Named after the Greek philosopher who lived nearly 2600 years ago, the Pythagorean theorem is as good as math theorems get (Pythagoras also started a religious movement). It's simple. It's beautiful. It's powerful. Common Core Standards: 8.G.B.7, 8.G.B.8

Pursuit_of_a_Pythagorean_proof

An exploration which allows the reader to choose his or her own path to a proof of the Pythagorean theorem.​

Pythagorean_theorem_proofs

The Pythagorean theorem is one of the most famous ideas in all of mathematics. This tutorial proves it. Then proves it again... and again... and again. More than just satisfying any skepticism of whether the Pythagorean theorem is really true (only one proof would be sufficient for that), it will hopefully open your mind to new and beautiful ways to prove something very powerful. Common Core Standard: 8.G.B.6
