The COMPLEMENT OF AN ANGLE, or arc, is the remainder obtained by subtracting the angle or arc from 90°. Thus the complement of 45° is 45°, and the complement of 31° is 59°. When an angle, or arc, is greater than 90°, its complement is negative.... Plane Trigonometry - Pàgina 14

...Complement of an Angle is 90° minus the angle. Thus, the complement of 30° is 60°. 2. It follows that, if the angle is greater than 90°, its complement is negative. Thus, the complement of 120° is 90° - 120° = -30°. 3. The acute angles of a right triangle are complements of each other....
