what is transversal

In geometry, a transversal is a line that intersects two or more lines in the same plane at two distinct points). When a transversal intersects two lines, it produces various types of angles in pairs, such as consecutive interior angles, corresponding angles, and alternate angles. A transversal produces eight angles, four of which are interior angles between the two lines, and four of which are exterior angles). When two parallel lines are cut by a transversal, it produces several congruent supplementary angles, such as corresponding angles, alternate interior angles, and consecutive interior angles. When two lines are cut by a transversal, the pairs of angles on either side of the transversal and outside the two lines are called the alternate exterior angles.
