# The Pythagorean Theorem: Understanding c² = a² + b² The equation c² = a² + b² is one of the most famous and foundational formulas in mathematics. Known as the Pythagorean Theorem, it describes a fundamental relationship in right triangles, where c represents the length of the hypotenuse (the side opposite the right angle), and a and b are the lengths of the other two sides. ## What Is the Pythagorean Theorem? The Pythagorean Theorem states that in any right-angled triangle, the square of the hypotenuse is equal to the sum of the squares of the other two legs:
