Linear pairs are the pair of angles that form when a line intersect another line.
supplementary means that the angles add up to 180.

So C or D?

anonymous · Answer

sorry for the late response but it's not reversible, while all linear pairs of angles are supplementary aka they add up to 180 not all pairs of angles that add up to 180 are linear pairs. Think about the angles made with a transverse line crossing two parallel lines.
