Parallel Lines Cut by a Transversal Proof

What is the Alternate Interior Angle Theorem?

• If two parallel lines are cut by a transversal, then the resulting alternate interior angles are congruent .

• If two angles are congruent, they are on parallel lines.

• If two parallel lines are cut by a transversal, then the angles are all congruent

• If two alternate interior angles are congruent, the lines are parallel.
