Explanation:

A contrapositive of a statement "If P, then Q" is "If not Q, then not P". For the given statement "If a quadrilateral has two pairs of parallel sides (P), then it's a parallelogram (Q)", the contrapositive swaps and negates both parts: "If it's not a parallelogram (not Q), then it doesn't have two pairs of parallel sides (not P)".

Answer:

If a quadrilateral isn't a parallelogram, then it doesn't have two pairs of parallel sides.
