The Pythagorean Theorem is a fundamental principle in geometry that specifically applies to right-angled triangles. It 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 (a² + b² = c²). This theorem is precisely what is used to calculate an unknown side length when the other two are known.
