15. 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.
