A circle intersected by a pair of parallel lines.
A polygon with 4 or more sides can have a pair of parallel sides.
quadrilateral
polygon
The number of pairs of parallel sides in a polygon varies depending on the type of polygon. For example, a rectangle has two pairs of parallel sides, while a trapezoid has one pair. Regular polygons, like a hexagon, typically do not have any pairs of parallel sides. Therefore, the total can range from zero to multiple pairs, depending on the specific polygon in question.
Any polygon with four or more sides can have a pair of parallel sides. It is also possible to to have non-polygonal shapes - eg a cigar-shape - that has parallel sides.
Any regular polygon of 2n sides where n>2.
A polygon with 4 or more sides can have a pair of parallel sides.

A kite for example.

rhombus
It is a deltoid or a kite.
Trapezoid
Any polygon with four or more sides can have a pair of parallel sides. It is also possible to to have non-polygonal shapes - eg a cigar-shape - that has parallel sides.
Any plane polygon having four or more sides may have one pair of parallel sides.
A parallogram has two pairs of parallel sides. A trapezoid has one pair of parallel sides. A regular octagon has four pairs of parallel sides. An irregular octagon may have from 3 pair to no pair of parallel sides.
