In a 45-45-90 triangle, the two legs are congruent, meaning they have the same length. The length of the hypotenuse is √2 times the length of each leg. This special relationship allows for easy calculations of side lengths when one leg is known. Thus, if each leg measures (x), the hypotenuse will measure (x\sqrt{2}).
