Using Alternate exterior angles to prove two lines are parallel

The video tutorial explains how to determine if two lines, M and N, are parallel using the theorem of alternate exterior angles. It demonstrates setting up and solving an equation to find the value of X that makes the lines parallel. The process involves assuming the angles are equal, forming an equation, and solving for X. The tutorial concludes that when X equals 29, the lines are parallel, illustrating the application of alternate exterior angles in proving parallelism.
