Given a statement like "if P, then Q", the contrapositive statement is "if not Q, then not P".

A statement and its contrapositive are logically equivalent, so they are either both true or both false.

So, since the original statement is the definition of supplementary, it is true, and so is its contrapositive, which is

"if the sum of two angles isn't 180, they are not supplementary"
