They are congruent.

Front

If two parallel lines are cut by a transversal, what can be said about the same-side interior angles?

Back

They are supplementary.

Front

What is the Corresponding Angles Postulate?

Back

If two parallel lines are cut by a transversal, then each pair of corresponding angles is congruent.

Front

What is the Alternate Interior Angles Theorem?

Back

If two parallel lines are cut by a transversal, then each pair of alternate interior angles is congruent.

Front

What is the Same-Side Interior Angles Theorem?

Back

If two parallel lines are cut by a transversal, then each pair of same-side interior angles is supplementary.
