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 line segments are called the sides of the triangle, and the end points are called the vertices of the triangle. In English the term âtriangleâ is also applied to the figure formed by the three line segments. Figure 1. An equilateral triangle is a triangle with all three sides equal (Figure 1,a). In an isosceles triangle only two of the sides are equal (Figure 1,b). A triangle whose interior angles are all acute is called an acute triangle (Figure 1,c).
