Applying same side interior and alternate interior theorems to solve for x and y

The video tutorial explains the properties of parallel lines and transversals, focusing on angle relationships. It covers alternate interior angles, which are equal, and same side interior angles, which are supplementary. The tutorial demonstrates solving for variables using these relationships, providing a clear understanding of how to apply these concepts in geometry.
