Question

Please, if you can, answer me a.s.a.p. b/c i need this info for my project =]

Answer 1

He discovered it by building a square out of each of the three sides of a right-angle triangle

Answer 2

The history of the Pythagorean theorem that bears Pythagoras's name is complex. Whether Pythagoras himself proved this theorem is not known, as it was common in the ancient world to credit a famous teacher with the discoveries of his students. The earliest known mention of Pythagoras's name in connection with the theorem occurred five centuries after his death, in the writings of Cicero and Plutarch.

Also, there are many ancient references to the facts stated in the Pythagorean theorem. Egyptian and Chinese tablets and writings show that they knew the theorem. It is also known that Pythagoras went into Egypt and after he came back he soon had the formula.

Though evidence exists that question whether Pythagoras created and solved the theorem, he is attributed to proving the theorem.

Answer 3

He invented the Theory for calculating the angles of the right angled triangle.
