Lesson 7-1 TakeAways Know how to locate and identify Corresponding Angles, Alternate Interior Angles, and Same-Side Interior Angles Corresponding Angles Postulate: If two parallel lines are cut by a transversal, then the corresponding angles are congruent. Alternate Interior Angles Theorem: If two parallel lines are cut by a transversal, then the alternate interior angles are congruent. Same-Side Interior Angles Theorem: If two parallel lines are cut by a transversal, then the same-side interior angles are supplementary.
