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.
A right triangle (or right-angled triangle, formerly called a rectangled triangle) has one of its interior angles measuring 90Â° (a right angle). The side opposite to the right angle is the hypotenuse, the longest side of the triangle.
