Which of the following describes a four sided figure that has no two sides parallel?

A four-sided figure with no two sides parallel is best described as a trapezium (in some regions referred to as a non-parallel quadrilateral). This geometric classification indicates that all four sides are distinct in orientation and length.

While other figures such as a square, rhombus, and rectangle have specific properties, all of which include at least one pair of sides that are parallel, a trapezium defies this rule. In a trapezium, the sides do not conform to any parallel alignment, making it a unique shape within the quadrilateral family.

The properties of common quadrilaterals include parallel sides in rectangles and squares, where opposite sides are equal and parallel. Rhombuses share this characteristic as well, with all sides being of equal length and opposite sides staying parallel. Thus, the trapezium stands out as the only option among those listed that clearly defines a shape with no parallel sides.
