Transversal t intersects two parallel lines, a and b.

In geometry, a transversal line is a line that passes through two or more other coplanar lines at different points.

In Euclidean geometry if lines a and b are parallel, and line t intersects lines a and b, then corresponding angles formed by line t and the parallel lines are congruent.

Alternate exterior angles created by a transversal of two lines.

Alternate interior angles created by a transversal of two lines.

[edit] Alternate angles

A transversal line creates alternate angles. The alternate interior angles are on opposite sides of the transversal line and inside the lines being transversed. Alternate exterior angles are on opposite sides of the transversal line and outside the lines being transversed. For it to be a true transversal line, it must interect two parallel lines. This creates several angle patterns.
