 Figure 1: Alternate Interior Angles

Alternate angles are angles that are on different sides of a transversal. A transversal is a line that intersects two other lines. Alternate interior angles are between the two lines (see figure 1). Alternate exterior angles are outside the two lines (see figure 2).

See also the Alternate Exterior Angles Theorem and the Alternate Interior Angles Theorem.
