Alternate Interior Angle Theore

Summary: If two parallel lines are cut by a transversal, alternate interior angles are formed. A letter Z is formed by the parallel lines are cut by the transversal. The opposite interior angles are congruent. The angle touching the transversal and the parallel line, are the angles that are congruent.
