Line t is a transversal here. Lines l and m are not transversals. Transversal - A line that intersects two or more coplanar lines at distinct (different) points. Line t is a transversal here. Lines l and m are not transversals. Angles 3, 4, 5, 6 are referred to as INTERIOR ANGLES because they are between or on the inside of lines l and m. Angles 1, 2, 8, 7 are referred to as EXTERIOR ANGLES because they are on the outsides of lines l and m.
