A shape that has two parallel sides? - Answers

There are many shapes with parallel sides: e.g. most regular quadrilaterals like Squares, Rectangles and Parallelograms have parallel sides, and so do quite a few regular polygon. But what is a parallel side (or line)? These are two line which are exactly the same length apart and must always be straight and consequently will never meet, no matter how far they extend. For example, train tracks are often parallel (until they bend for the train to turn left or right). They would have to be parallel, because the distance between the train's wheels is always going to be the same. Many shapes have "sets" of parallel sides, like a rectangle has two sets and a hexagon has six. Sets of Parallel lines (or sides) are distinguished by an arrow pointing in one direction of both lines. Note: Irregular polygons with 5 or more sides are also candidates.
