Front

What are complementary angles?

Back

Two angles that add up to 90 degrees.

Front

What are supplementary angles?

Back

Two angles that add up to 180 degrees.

Front

What are vertical angles?

Back

Angles that are opposite each other when two lines intersect; they are always equal.

Front

What are adjacent angles?

Back

Two angles that share a common side and a common vertex.

Front

If two angles are complementary and one angle measures 30 degrees, what is the measure of the other angle?

Back

60 degrees.

Front

If two angles are supplementary and one angle measures 100 degrees, what is the measure of the other angle?

Back
