Comparisons of "trapezium" in both British and American English.

The word trapezium, used to describe a geometric shape, has two contradictory meanings:

• (outside the US and Canada) – a quadrilateral with at least one pair of parallel sides, known in the US as a trapezoid.
• (in the US and Canada) – a quadrilateral with no parallel sides (a shape known elsewhere as a general irregular quadrilateral).

The word trapezium can also mean:

• Trapezium (bone), a bone in the wrist
• Trapezium (astronomy), a group of stars in the Orion Nebula
• Trapezium (play), a play by Henry Rathvon
