Sides and Angles x The hypotenuse is always the longest side of the right triangle and is across from the right (90°) angle. The adjacent side is the side that forms the angle (x) with the hypotenuse. The opposite side is the side across from the angle (x). hypotenuse adjacent opposite xhypotenuse adjacent opposite We identify the different sides of a right triangle based on the angle we are given.
