What is a transversal in geometry?

A transversal in geometry is defined as a line that intersects two or more lines at distinct points. This means that when a transversal crosses other lines, it creates various angles, which can help in understanding the relationships between those lines and the angles formed. For example, when a transversal intersects two parallel lines, it creates corresponding angles that are equal, alternate interior angles that are also equal, and so forth.

This concept is central in the study of parallel lines as well as in solving problems involving angle relationships. The clear distinction of crossing multiple lines at different points distinguishes this definition from other possible types of lines, like those that might only run parallel or connect midpoints, which do not fulfill the criteria of a transversal.
