Exploring Parallel Lines and Transversals

This video tutorial covers the concept of parallel lines and transversals, explaining the types of angles formed when a transversal cuts through parallel lines. It includes definitions and examples of corresponding, alternate interior, alternate exterior, same side interior, and vertical angles. The tutorial also provides practice in classifying angles as congruent or supplementary and finding missing angles using these concepts. A highlighter trick is introduced to help verify angle relationships, ensuring a comprehensive understanding of the topic.

What are parallel lines?

• Lines that never meet
