If the lines AB and CD are parallel, then angles C and E are D) supplementary meaning they add up to 180 degrees.

Answer:

D) supplementary

Step-by-step explanation:

Angles c and e will be same-side interior angles.  This is because they are inside the block of parallel lines and on the same side of the transversal.

If the two lines are parallel, then same-side interior angles are supplementary.
