A squared plus B squared equals C squared

The equation \(A^2 + B^2 = C^2\) describes the relationship in a right triangle, where \(A\) and \(B\) are the lengths of the two shorter sides (legs), and \(C\) is the length of the longest side (hypotenuse). It states that the square of the hypotenuse equals the sum of the squares of the other two sides. This formula helps calculate one side when the other two are known and is fundamental in geometry, trigonometry, and various practical applications like construction and navigation.
