# Exterior angles formed by Straight lines and their Transversal

The angles formed externally when two or more straight lines are intersected by their transversal are called exterior angles formed by straight lines and their transversal.

The intersection of two straight lines and their transversal is basic special case of forming transversal in geometrical mathematics. In this case, four outer angles are formed when two parallel (or) nonparallel lines are cut by their transversal and they called exterior angles of the transversal.
