Parallel Lines & Angles

Front

What are alternate angles?

Back

Alternate angles are angles that are on opposite sides of a transversal and are equal when the lines are parallel.

Front

What is the relationship of corresponding angles?

Back

Corresponding angles are equal when two parallel lines are cut by a transversal.

Front

If angle 6 is 25 degrees, what is angle 7?

Back

Angle 7 is 155 degrees.

Front

What is the measure of angle x if it is supplementary to 59 degrees?

Back

x = 121°.

Front

What angle pair is formed when two lines intersect?

Back

Vertical angles are formed when two lines intersect and they are equal.

Front

What are supplementary angles?

Back

Supplementary angles are two angles whose sum is 180 degrees.

Front

What are complementary angles?

Back

Complementary angles are two angles whose sum is 90 degrees.

Front

What is the measure of corresponding angles when two parallel lines are cut by a transversal?

Back

Corresponding angles are equal.

Front

What is the sum of alternate interior angles?

Back

Alternate interior angles are equal when the lines are parallel.
