This proof is the famous "rearrangement" proof of the Pythagorean Theorem, which involves movement and rearrangement of shapes. It will also involve algebraic skills as well, as certain calculations are required in this proof. As this is mostly visual & does not involve complex equations, this demo will be able to fascinate your students and pull them into the fascinating world of mathematics!
