A right triangle is a triangle with one right angle, that is, one angle that measures 90°. By convention we usually call a right triangle ΔABC, and give the angles and sides the labels shown in this picture. The vertex of the right angle is labeled with the capital letter C; the other vertices are labeled A and B.
