Angle Pairs Practice

Front

What is a vertical angle?

Back

Vertical angles are the angles opposite each other when two lines intersect. They are always equal in measure.

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.

Front

What is an adjacent angle?

Back

Adjacent angles are two angles that share a common side and a common vertex but do not overlap.

Front

What is a linear pair of angles?

Back

A linear pair of angles consists of two adjacent angles that form a straight line, adding up to 180 degrees.

Front

If m∠1 = 30°, what is m∠2 if m∠1 and m∠2 are complementary?

Back

m∠2 = 60°.

Front

If m∠3 = 150°, what is m∠4 if m∠3 and m∠4 are supplementary?

Back

m∠4 = 30°.

Front

What is the relationship between two angles that are both 45°?

Back

They are vertical angles and are equal.

Front

If two angles are adjacent and one measures 70°, what is the maximum measure of the other angle if they are supplementary?

Back

The maximum measure of the other angle is 110°.

Front

What is the sum of the measures of two complementary angles?

Back

The sum is 90 degrees.
