The simplest would be an octagon; but you could also have polygons with 9 or more sides.
a trapizoid is the 2d shape for that
I do not believe that such a figure can exist: it must have at least two pairs of parallel sides.
A shape with two pairs of parallel sides is ........ a parallelogram!
shape no pairs of perpendicular sides
It is a square or a rectangle
A square
A parallelogram has two pairs of parallel sides.
An equilateral hexagon would work. It has more than 2 pairs of parallel sides though. There is no shape with only 2 pairs of parallel sides besides a parallelogram.
It is a shape which has two pairs of PARALLEL sides. Parallel sides - parallelogram. Get it?
It can have anywhere between 0 and 12 pairs of parallel sides.
rhombus
A hexagon.
