This video tutorial introduces the concept of a transversal in geometry, a line that intersects two or more coplanar lines, and explores the various types of angles formed by such intersections. It covers vertical angles, corresponding angles, alternate interior and exterior angles, and consecutive interior and exterior angles, explaining their properties and relationships, especially when the intersected lines are parallel.

What is a transversal?

• A line that is parallel to another line

• A line that intersects two or more coplanar lines

• A line that forms a right angle

• A line that intersects only one line
