We measure angles in degrees, and use the symbol ° to represent degrees We use the abbreviation m for the measure of an angle So if ∠A is 27°, we would write m ∠ A = 27 If the sum of the measures of two angles is 180°, then they are called supplementary angles In Figure \(\PageIndex{3}\), each pair of angles is supplementary because.

A triangle has side lengths of 5, 12, and 13 inches The angle measures are 90°, 23, and 67. "Anglebased" special right triangles are specified by the relationships of the angles of which the triangle is composed The angles of these triangles are such that the larger (right) angle, which is 90 degrees or π / 2 radians, is equal to the sum of the other two angles The side lengths are generally deduced from the basis of the unit circle or other geometric methods. Because it is a right triangle one angle is obviously 90° The other two are approximately 3687° and 5313° An everyday example The 345 triangle is useful when you want to determine if an angle is a right angle For example, suppose you have a piece of carpet and wish to determine if one corner of it is 90° First measure along one edge.
