Answer 1

A. c ║d, Converse of the Corresponding Angles Postulate

Explanation:

Line B (including numbers 1-8) can be ignored in the diagram.

When 2 angles are located on one side of the transversal (line a) and are also located below on the same side of one of the parallel lines (below lines c and d) they are called corresponding angles.

Hope that makes sense.
