Exploring the Proofs of the Pythagorean Theorem

Professor Dave demonstrates a proof of the Pythagorean theorem using geometric shapes. He constructs a right triangle and duplicates it to form squares, calculating their areas. By setting up an equation relating these areas, he shows how the Pythagorean theorem emerges. The video concludes with encouragement to explore other proofs.
