How to Find an angle using alternate interior angles

In this video tutorial, viewers learn how to find an angle using alternate interior angles. Make sure that the angles are alternate interior angles. Alternate interior angles are angles that are on the inside of the parallel lines, and on the opposite side of the transverse. The transverse is the line that passe through the two parallel lines. If both angles are inside the line and are opposite to the transverse, then they are alternated interior angles. If you know two angles are alternate interior angles, then they are congruent. This video will benefit those viewers who are struggling in math, especially this unit and would like to learn how to find an angle using alternate interior angles.
