A trapezoid, by definition, has one pair of parallel sides and one pair of non-parallel sides.

Many polygons have exactly 1 pair of parallel sides. For instance, regular hexagons do, too.

Actually, therapsis, a regular hexagon has 3 pairs of parallel sides. But, you are right, many polygons (in fact, an infinite amount) have one pair of parallel sides. However, the only named one I know of is the trapezoid.

I went to wikipedia to see if there was a name for such a type of figure … I didn’t happen to find it, but I remembered that browsing the math articles on wikipedia was one of the most intelligently rewarding uses of it I’ve found. Both my parents have math degrees so I might have been raised differently? Whatever, it still seems nice like that.
