The term corresponding angles is often used when two lines are cut by a third line, a transversal.
In the figure above, line t is a transversal cutting lines k and l, and there are four pairs of corresponding angles:
1 and 5
2 and 6
3 and 7
4 and 8
The term corresponding angles is also sometimes used when making statements about similar or congruent polygons. For example, in the figure below featuring two similar pentagons, A and V are corresponding angles.
