Any shape wit four of more sides can have one pair of parallel sides.
A square
A polygon with 4 or more sides can have a pair of parallel sides.
A right hendecagon can have no parallel sides because there are eleven sides to a hendecagon. It is not a requirement that there be any pairs of parallel sides in an irregular hendecagon, although there could be one or more pairs.
Strictly speaking you cannot have one parallel side - you must have one pair. Any irregular polygon with four or more sides can have a pair of parallel sides. Most have no specific names - the only one that does is a trapezium.
Not exactly. A trapezoid has exactly one pair of parallel sides -- no more and no less.
Any plane polygon having four or more sides may have one pair of parallel sides.
Any shape wit four of more sides can have one pair of parallel sides.
2It has one pair more because a parallelogram has two pairs of parallel sides whereas a trapezoid only has one pair of opposite parallel sides of different lengths.
square
A trapezoid has one pair of parallel sides.
The more common definition of a trapezoid (or trapezium, outside of North America) is a four-sided figure with exactly one pair of parallel sides. By this definition, figures with two sets of parallel sides such as a rectangle are nottrapezoids.Some mathematicians use a more general definition that allows for one or more pair of parallel sides. By this definition, a rectangle, square, or rhombus would be considered as special cases of a trapezoid.

A square
A trapezium or parallelogram. A pentagon can have a pair of parallel sides. Polygons with 6 or more sides can have two (or more) pairs of parallel sides.
A trapezoid is a quadrilateral (meaning it has 4 sides) with 1 pair of parallel sides (meaning only 1 side is parallel to another on the figure).
Any polygon with four or more sides can have parallel sides.
