Who is the author of the famous theorem “a² + b² = c²” in a right-angled triangle?

Pythagoras

The Pythagorean theorem is one of the cornerstones of geometry, attributed to Pythagoras, a mathematician from ancient Greece. This principle, which establishes a fundamental relationship between the sides of a right-angled triangle, was known in several ancient cultures well before Pythagoras, but it is he who is credited with it in the Western world. Beyond geometry, this theorem finds applications in various fields such as physics, architecture, and navigation. The influence of the Pythagorean theorem goes far beyond mathematics, testifying to the depth of human thought through the ages.
