For example 30 o and 60 o, 40 o and 50 o, 20 o and 70 o, etc. Since a right angle doesn’t need another angle to complete the 90 o, it doesn’t have a complement and can’t be called a complement by itself. Complementary comes from Latin completum meaning “completed”, because the right angle is thought of as being a complete angle. So, complement of any angle is the value obtained by subtracting it from 90 0. If two angles are complementary of each other, then each angle is: A. an obtuse angle.
