Front

What are corresponding angles?

Back

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

Name a pair of corresponding angles.

Back

∠2 and ∠10.

Front

What are same-side interior angles?

Back

Same-side interior angles are pairs of angles that are on the same side of the transversal and inside the two parallel lines. They are supplementary.

Back

∠6 and ∠11.

Front

What are alternate exterior angles?

Back

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