Learn How to Find the Missing Value to Prove Lines are Parallel

The video tutorial explains how to determine if two lines are parallel by analyzing angle relationships. It introduces the concept of consecutive interior angles and their role in proving parallel lines. The tutorial demonstrates solving for variables using given angle measures, specifically focusing on vertical angles and supplementary angles. By solving the equation 2X + 50 + 60 = 180, the value of X is found to be 35 degrees, proving the lines are parallel.
