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 acute triangle is composed of three acute angles, the same as saying that all three of its angles are smaller than 90Â°. 1  A right triangle (or right-angled triangle) has one 90Â° internal angle (a right angle). 2  The side opposite to the right angle is the hypotenuse; it is the longest side in the right triangle.
