Angle pairs (parallel lines)

Front

What are corresponding angles?

Back

Angles that are in the same position on parallel lines in relation to a transversal. They are equal in measure.

Front

What is the relationship between alternate interior angles when lines are parallel?

Back

Alternate interior angles are congruent.

Front

Define vertical angles.

Back

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

Front

What are consecutive interior angles?

Back

Angles that are on the same side of the transversal and between the two lines. They are supplementary when the lines are parallel.

Front

If two parallel lines are cut by a transversal, what can be said about corresponding angles?

Back

They are equal.

Front

What is the measure of angle A if it is a corresponding angle to angle B which measures 70 degrees?

Back

Angle A measures 70 degrees.

Front

If angle 1 and angle 2 are alternate exterior angles and angle 1 measures 110 degrees, what is the measure of angle 2?

Back

Angle 2 measures 110 degrees.

Front

What is the sum of consecutive interior angles when lines are parallel?

Back

The sum is 180 degrees.

Front

If two angles are supplementary and one angle measures 90 degrees, what is the measure of the other angle?

Back

The other angle measures 90 degrees.

Front

What is the relationship between alternate exterior angles when lines are parallel?

Back

Alternate exterior angles are congruent.
