Using Consecutive Interior Angles to Prove Parallel Lines

The video tutorial explains how to determine if lines are parallel by examining consecutive interior angles. It begins by discussing the concept of parallel lines and the importance of not assuming lines are parallel without proof. The tutorial then introduces consecutive interior angles and their supplementary nature. It explains the Converse Theorem, which states that if these angles sum to 180 degrees, the lines are parallel. The video demonstrates solving for X in an equation to prove the angles are supplementary, thus proving the lines are parallel.
