View Euclid Pythagorean Theorem Proof Gif. Euclid's proof now we can rotate the triangle without changing it. Pythagoras was a teacher and philosopher who lived some 250 years before euclid, in the 6th century b.c.
Proof of the pythagorean theorem using algebra.
I am pretty sure that this one is euclid's proof. The pythagorean theorem is one of the most popular to prove by mathematicians, and there are many proofs available (including one from james garfield). For any finite set of prime numbers, there exists a prime number not in that set. Given its long history, there are numerous proofs (more than 350) of the pythagorean theorem, perhaps more than any other theorem of geometric proofs.
