who created the pythagorean theorem

The Pythagorean theorem is named after the ancient Greek mathematician and philosopher Pythagoras of Samos (c. 570 – c. 495 BC), who is traditionally credited with its discovery. However, the theorem was known and used by earlier civilizations such as the Babylonians and Indians centuries before Pythagoras lived. These earlier cultures had practical knowledge of the relationship between the sides of right-angled triangles, but Pythagoras or his school is often credited with providing a formal proof and popularizing the theorem in the Western world. It is also important to note that Pythagoras left no written records, and much of what is known about his contributions comes from his followers and later historians, making the precise origin of the theorem somewhat uncertain. The theorem states that in a right-angled triangle, the square of the hypotenuse equals the sum of the squares of the other two sides (a2+b2=c2a^2+b^2=c^2a2+b2=c2).
