The Alternate Exterior Angles Theorem states that if a pair of parallel lines are cut by a transversal, then the alternate exterior angles are congruent.Question 15Select one:TrueFalse

If two parallel lines are cut by a tranversal, then alternate interior angles are congruent  True False

If two lines are cut by a transversal so that a pair of consecutive interior angles (same side interior angles) are congruent, then the lines are parallel.

What can you conclude about the interior angles formed when two parallel lines are cut by a transversal?Each pair of alternate interior angles is .Each pair of same-side interior angles is .

When two parallel lines are cut by a transversal, interior angles are supplementary.
