Alternate Interior Angles - Transversals

The video tutorial explains how to determine the measures of angles formed by two parallel lines intersected by a transversal. It covers the concepts of vertical angles, alternate interior angles, and supplementary angles, using a problem where one angle is given as 135 degrees. The tutorial demonstrates how to identify all angles as either 135 or 45 degrees, emphasizing the properties of parallel lines and transversals.
