Transversal and Angle Relationships

Mr. Dell explains how to find angle measurements when parallel lines are cut by transversals. Using given angles, he calculates the remaining angles by applying concepts like straight angles, same side interior angles, and alternate interior angles. The video covers the step-by-step process of determining each angle, supported by definitions and conjectures.
