Say (9) show 11 ??
In Chambers, trapezoid is defined as 'a quadrilateral with no sides parallel; one with two sides parallel.'
Is it (9) or (11) as shown?
trapezoid
ˈtrapɪzɔɪd,trəˈpiːzɔɪd/Submit
noun
1.
GEOMETRYBRITISH
a quadrilateral with no sides parallel.
(Called a trapezium in the UK. Both US and UK definitions of trapezium and trapezoid are swapped over.)
(geometry, US, four-sided polygon with no sides parallel and no equal sides): The terms trapezium and trapezoid have swapped meanings in the US and Canada as compared with the rest of the world. The British etc. usage is older; the American usage is traceable to the two entries having been accidentally exchanged in Charles Hutton's Mathematical and Philosophical Dictionary of 1795.
the confusion is because it is termed differently in the USA compared to the UK
