 * Alternate Interior Angles.png

Corresponding Angles are the angles in equivalent positions on the two lines cut by a transversal with respect to that transversal.

In the above figure, the corresponding angles with respect to the transversal $EF$ are:
 * $\angle AHJ$ and $\angle CJF$
 * $\angle AHE$ and $\angle CJH$
 * $\angle BHE$ and $\angle DJH$
 * $\angle BHJ$ and $\angle DJF$
