My daughter has been working on geometry this year and needed a little more practice working on complementary and supplementary angles. I wanted to share these free Complementary and Supplementary Angles Worksheets with you today!
She had to define and draw examples of these. And, she also had to determine the measures of complementary and supplementary angles based on diagrams and the information provided.
- Two angles are complementary if the sum of their measure is 90°.
- Two angles are supplementary if the sum of their measure is 180°.
I also wanted her to become familiar with how large/small angles are, so there are protractors where she had to draw the measure of the angle (right on top of the illustration). As you can see in the screenshot below, I tilted some of the protractors to make the point that it doesn’t matter which direction an angle is facing.
