Exploring Angles Formed by Parallel Lines and Transversals

This video tutorial covers the concepts of parallel lines and transversals, focusing on the different types of angle pairs formed when a transversal cuts through parallel lines. It explains alternate interior, alternate exterior, corresponding, and same side interior angles, using diagrams and color coding to illustrate congruence and supplementary relationships. The video includes practice questions and algebraic problems to reinforce understanding of these geometric concepts.

What is a transversal?

• A line that is parallel to another line

• A line that intersects two or more lines

• A line that is perpendicular to another line

• A line that forms a right angle
