Pythagorean Theorem

+The [Pythagorean Theorem](/wiki/pythagorean_theorem) uncovers a fundamental relationship within a [right triangle](/wiki/right_triangle). It states that the square of the longest side (hypotenuse) is equal to the sum of the squares of the other two sides ($a^2 + b^2 = c^2$), a cornerstone of geometry and measurement.
