Trapezoid
a rectangle is a shape that has two sets of parallel lines a trapezoid only has to have one set of parallel lines
A triangle, as it only has three lines and the only two that are possible touch at the top.
A square or rectangle has two sets of parallel lines. Stop signs technically have 4 short sets o parallel lines. Hexagon could have 3 sets, etc. All of which are polygons, though not all polygons have parallel lines.
A shape that has all parallel sides, like a square, rectangle, or a rhombus. A trapazoid wouldn't be one because only one set of lines are parallel.

A parallelogram has 1 pair of parallel lines that is also regular. See the related link.

Triangles, Circles, Ellipses Only triangle if you only want polygons.

If you mean one pair of parallel lines, then you're talking about a trapezoid.

An isosceles trapezoid would seem to fit the given description.
Answer: trapezoid Answer: There is no such thing as "one parallel side". Parallel refers to the relationship between TWO lines - so, two lines can either be parallel, or not be parallel. A shape can have one PAIR of parallel sides (e.g. a trapezoid), two PAIRS of parallel sides (e.g., a parallelogram), or more than that (e.g., a regular hexagon has three pairs of parallel sides).
A trapezium (has only one pair of unequal parallel lines).
