Looking for a Complementary Angles Worksheet?

Complementary angles add up to 90°. This means that if you were to divide a right angle into several smaller angles, the total sum of the complementary angles would be 90°.

This worksheet provides students with the opportunity to calculate the size of the missing complementary angle on a variety of right angles. 

An answer key is included with your download to make marking fast and easy!
