Angle Relationships Review

Front

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.

What is the relationship between consecutive interior angles?

Back

Consecutive interior angles are supplementary, meaning their measures add up to 180°.

Front

How do you find the measure of an unknown angle when given a linear pair?

Back

The measures of angles in a linear pair are supplementary, so you can subtract the known angle from 180° to find the unknown angle.

What is the measure of an angle that is complementary to a 75° angle?

Back

The measure of the complementary angle is 15°, since complementary angles add up to 90°.

If two angles are alternate interior angles, what can be said about their measures?

Back

Alternate interior angles are equal in measure when two parallel lines are cut by a transversal.

What is the value of x if ∠A + ∠B = 180° and ∠A = 120°?

Back

x = 60°, since ∠B must be supplementary to ∠A.
