Missing Angles Practice

Front

What is a missing angle?

Back

A missing angle is an angle that needs to be calculated based on the information given about other angles in a geometric figure.

Front

What are complementary angles?

Back

Complementary angles are two angles whose measures add up to 90 degrees.

Front

What are supplementary angles?

Back

Supplementary angles are two angles whose measures add up to 180 degrees.
