Front

What are vertical angles?

Back

Angles that are opposite of each other when lines intersect.

Front

What are adjacent angles?

Back

Angles that share a common side and vertex but do not overlap.

Front

What is a linear pair of angles?

Back

Two adjacent angles that form a straight line and add up to 180°.

Front

What are complementary angles?

Back

Two angles that add up to 90°.

Front

What are supplementary angles?

Back

Two angles that add up to 180°.
