What is a corresponding angle? in a set of parallel lines with a transversal line

When a set of parallel lines is intersected by a
transversal line we get sets of corresponding angles. These are angles which lie on the
same side of the transversal and both of them are either above or below the parallel
lines.

In total there are 4 sets of corresponding angles
formed when a transversal intersects a set of parallel
lines.

Transversal lines can intersect sets of lines which
are not parallel also and form similar corresponding angles. The only difference in the
case of parallel lines is that the angles in each set of corresponding angles are
equal.

Corresponding angles are sets of
angles created when the transversal intersects the parallel lines. They lie on the same
side of the transversal and both of them are either above of below the parallel lines.
