Transversal Lines and Angle Pairs

Front

What are alternate interior angles?

Back

Angles that are located inside the parallel lines and on opposite sides of the transversal. They are congruent.

Front

What are corresponding angles?

Back

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

Front

What are supplementary angles?

Back

Two angles that add up to 180°.

Front

What are consecutive interior angles?

Back

Angles that are on the same side of the transversal and inside the parallel lines. They are supplementary.

Front

What are alternate exterior angles?

Back

Angles that are located outside the parallel lines and on opposite sides of the transversal. They are congruent.

Front

If ∠3 and ∠6 are alternate interior angles, what can be said about their measures?

Back

They are equal in measure.

Front

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

Back

They are equal in measure.

Front

What is the relationship between same side interior angles?

Back

They are supplementary, meaning they add up to 180°.

Front

What type of angles are formed when a transversal crosses two parallel lines?

Back

Alternate interior angles, corresponding angles, alternate exterior angles, and same side interior angles.

Front

If angle Q and angle B are corresponding angles, what can be inferred?

Back

Angle Q is equal in measure to angle B.
