The Pythagorean Theorem is a cornerstone of geometry, a fundamental mathematical principle that describes the relationship between the sides of a right-angled triangle. At its core, the theorem states that the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides. This elegant and powerful relationship, often expressed as a² + b² = c², has captivated mathematicians, scientists, and builders for millennia. Its simplicity belies its profound implications and wide-ranging applicability.
