Document Summary
Two angles of a triangle are congruent if the measure of the two angles is the same. The word trigonometry comes from the greek words trigonon , meaning triangle, and the word. Every triangle has three angles and three sides. The sum of the measures of the three angles is equal to. Similarly, two sides of a triangle are congruent if the lengths of the two sides are equal. We can classify triangles based on the measure of their angles or the lengths of their sides. We start by classifying triangles based on their angle measures. A triangle with three acute angles is called an acute triangle. A triangle with one obtuse angle is called an obtuse triangle. A triangle with one right angle is called a right triangle. The side opposite the right angle of a right triangle is called the hypotenuse and the two other sides of a right triangle are called legs.
