Pythagorean Theorem -
Since at least the first century BC, Pythagoras has commonly been given credit for discovering the Pythagorean theorem, a theorem in geometry that states that "in a right-angled triangle the square of the hypotenuse is equal [to the sum of] the squares of the two other sides." -
At Croton, he founded the philosophical school of Pythagoreanism, whose practitioners adhered to a strict, disciplined way of life. Pythagoras acquired great political influence in Magna Graecia; later biographers tell fantastical stories of the effects of his eloquent speech in leading the people of Croton to abandon their luxurious and corrupt way of life and devote themselves to the purer system which he came to introduce.
