Exploring Transversals in Geometry

This video tutorial covers the geometry of angles formed when parallel lines are intersected by a transversal. It introduces key concepts such as transversals, vertical angles, corresponding angles, alternate interior angles, and alternate exterior angles. The video explains how these angles are congruent or supplementary and provides examples to illustrate these properties. Students are guided through exercises to identify and calculate angle measurements using these concepts.

What is a transversal?

• A line that intersects two other lines at different points

• A line that is parallel to two other lines

• A line that intersects one other line at the same point

• A line that does not intersect any other lines
