Pairs of Angles. When parallel lines get crossed by another line (which is called a Transversal ), you can see that many angles are the same, as in this example: These angles can be made into pairs of angles which have special names. Click on each name to see it highlighted: Now play with it here.

Parallel lines are lines in the same plane that go in the same direction and never intersect. When a third line, called a transversal, crosses these parallel lines, it creates angles. Some angles are equal, like vertical angles (opposite angles) and corresponding angles (same position at each intersection). Created by Sal Khan.

Consecutive angles are the angles that touch each other, the top and bottom corners, and they are inside the parallel lines, although some teachers say they can also be outside the parallel lines.

When the lines are parallel, the measures are equal. ∠1 and ∠2 are alternate interior angles. ∠3 and ∠4 are alternate interior angles. Alternate interior angles are " interior " (between the parallel lines), and they " alternate " sides of the transversal. Notice that they are not adjacent angles (next to one another sharing a vertex).
