Every triangle has three sides and three angles, some of which may be the same. The sides of a triangle are given special names in the case of a right triangle, with the side opposite the right angle being termed the hypotenuse and the other two sides being known as the legs. All triangles are convex and bicentric.
The hypotenuse is the side of a right triangle that is directly across from the right angle (indicated by the black square in the picture at the left). The shorter sides of a right triangle are called the legs of the triangle (sides AB and BC in the picture at the right). Together the legs form the right angle of the right triangle. The medians of a triangle are line segments formed by connecting a vertex to the midpoint of the opposite side.
