Naming the Sides of a Right-Angled Triangle. The side opposite the right angle is called the hypotenuse. It is the largest side of a right-angled triangle. If you stand at A in the triangle ABC, the side BC is opposite to you and the side AB is next to you. We therefore say that BC is the opposite side to angle A and AB is the adjacent side to angle A.
