What are corresponding angles?

Back

Corresponding angles are pairs of angles that are in the same position on different parallel lines cut by a transversal. They are equal in measure.

Front

What is the sum of supplementary angles?

Back

The sum of supplementary angles is 180°.

Front

If angle 1 = 27°, what is the measure of angle 4 if they are corresponding angles?

Back

Angle 4 = 27°.

Front

What is the measure of the supplement of 45°?

Back

The supplement of 45° is 135°.

Front

What are alternate interior angles?

Back

Alternate interior angles are pairs of angles that are on opposite sides of the transversal and inside the two parallel lines. They are equal in measure.

Front

If m∠5 = 63°, what is the measure of angle 3 if they are supplementary?

Back

Angle 3 = 117°.

Front

What is the measure of angle 1 if it is given as 113°?

Back

m∠1 = 113°.

Front

What is the relationship between angles formed by a transversal cutting through parallel lines?

Back

The angles formed have specific relationships: corresponding angles are equal, alternate interior angles are equal, and consecutive interior angles are supplementary.

Front

What is the measure of a right angle?

Back

A right angle measures 90°.

Front

If two angles are complementary, what is their sum?

Back

The sum of complementary angles is 90°.
