What has four sides and no right angles and all sides are parallel?

Answer 1

Trapazium.

In North America, the term trapezium is sometimes defined as a quadrilateral with no parallel sides, though this shape is more usually called an irregular quadrilateral. The term trapezoid has been defined as a quadrilateral without any parallel sides in Britain and elsewhere, but this does not reflect current usage (the Oxford English Dictionary says "Often called by English writers in the 19th century")
