Understanding the Pythagorean Formula: The Foundation of Right Triangle Geometry When exploring the world of geometry, few formulas are as foundational and widely used as the Pythagorean Theorem, famously expressed as: a² + b² = c² This elegant yet powerful equation defines the relationship between the lengths of the sides of a right triangle. For those unfamiliar, it states that in any right-angled triangle, the square of the hypotenuse (the side opposite the right angle—often the longest side, denoted as c) is equal to the sum of the squares of the other two sides (a and b).
