What is an angle?

Back

An angle is formed by two rays (sides) that share a common endpoint (vertex). It is measured in degrees.

What is a complementary angle?

Back

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

Front

What is a supplementary angle?

Back

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