Using Alternate Interior Angles to Show Two Lines are Parallel

The video tutorial explains how to determine if two lines are parallel by examining the relationships between angles. It covers alternate interior, alternate exterior, corresponding, and consecutive interior angles, emphasizing that certain angles must be equal or sum to 180 degrees for lines to be parallel. The tutorial includes solving equations to find when angles are equal, verifying calculations, and exploring different values of X to understand their impact on angle equality and parallelism.
