The Pythagorean Theorem is a fundamental principle in mathematics that relates the lengths of the sides of a right triangle. Specifically, it states that the square of the length of the hypotenuse is equal to the sum of the squares of the lengths of the other two sides, expressed as $$c^2 = a^2 + b^2$$. This theorem is essential in various applications, including understanding geometric properties and calculations related to crystal structures in condensed matter physics.
