Utilize our printable complementary and supplementary angles worksheets to help build your child's skill at identifying complementary and supplementary angles, finding the unknown angles, using algebraic expressions to find angular measures, and more.
The geometry worksheets on this page can be used to introduce and review the concepts of complementary, supplementary angles, and vertical angles. Most worksheets on this page align with Common Core Standard 7.G.B.5.
Complementary angles are two angles whose sum is 90°. So, the complement of 50° is (90 – 50), that is 40°. The complement of 40° is just the reverse, which is 50°. Supplementary angles are two angles whose sum is 180°. It can also be called linear pair of angles. The sum of a pair of linear angles is always 180°.
In geometry, complementary angles are defined as two angles whose sum is 90 degrees. Two complementary angles when put together form a right angle. Learn the differences between complementary and supplementary angles.
Aim: I can determine the measure of Complementary, Supplementary, & Vertical Angles. 1) What is the supplement of a 42º angle? 2) What is the complement of a 83º angle?
Complementary angles are pairs of angles that add up to 90 degrees when combined. In other words, if you have two angles that are complementary to each other, the sum of their measures is 90 degrees. Mathematically, if ∠A and ∠B are complementary angles, you can represent this as: ∠A + ∠B = 90 degrees. Let one of the angles be x degrees.
Complementary angle are usually part of a right angle and add up to 90 degrees. These worksheets explain how to adjacent, supplementary, complementary, and vertical angles and how to find the number of degrees in an angle(s).
