Pythagorean Theorem Proofs
The Pythagorean Theorem, a cornerstone of geometry, asserts that in a right-angled triangle, the square of the length of the hypotenuse is equal to the sum of the squares of the lengths of the other two sides. Since its discovery by the ancient Greek mathematician Pythagoras, numerous proofs have been developed to elucidate and validate this fundamental principle. These proofs, ranging from algebraic to geometric demonstrations, serve to deepen our understanding of the theorem's underlying principles and highlight its universal applicability in various mathematical contexts.
