WebJan 20, 2024 · Right triangle definition. All triangles have interior angles adding to 180°. When one of those interior angles measures 90°, it is a right angle and the triangle is a right triangle. In drawing right triangles, the interior 90° angle is indicated with a little square in the vertex. Right triangle compared to non-right triangle. WebAll right triangles have two legs, which may or may not be congruent. The legs of a right triangle meet at a right angle. The other side of the triangle (that does not form any part of the right angle), is called the hypotenuse of the right triangle. This side of the right triangle will always be the longest of all three sides.
