Feb 19, 2009 · Parallelograms. Parallelogram: A quadrilateral with two pairs of parallel sides. We haven't technically defined what parallel means, but it means that the two segments never meet, even if you were to continue tem infinitely far. Known examples are for instance the left and the right side of a ladder, or the double lines you see on some freeways.
