Exploring Angle Relationships with Parallel Lines

This video tutorial by Mr. Weaver covers 8th grade module 7, lesson one on angle relationships and parallel lines. It explains the concepts of perpendicular and parallel lines, transversals, and the types of angles formed when a transversal intersects parallel lines. The lesson includes examples of classifying angle pairs as alternate interior, alternate exterior, or corresponding angles, and demonstrates how to find missing angle measures using these relationships.

What is the special notation used to indicate perpendicular lines?

• An arrowhead

• A small circle

• A right angle symbol

• A double line
