In geometry, what does a transversal do?

A transversal is a line that intersects two or more lines, typically in a plane. This interaction creates various angles of interest, such as corresponding angles, alternate interior angles, and alternate exterior angles, which are essential concepts in geometry. Understanding the function of a transversal is crucial in solving problems related to angles and the properties of parallel lines, as it leads to important conclusions about angle relationships. Thus, recognizing that the definition of a transversal centers on its ability to intersect lines is key to grasping fundamental geometric principles.
