A shape has four sides that each measure 5 centimetres and four right angles. Select all the names that this shape may correctly be given.
Explanation
The shape satisfies the four equal sides that one name demands and the four right angles that another demands at the same time, so both are honest descriptions of it alongside the tightest name of all. Treating the categories as sealed boxes is the error here, because shape names simply list conditions and one shape can meet several sets at once. The trapezoid claim fails on the reason it gives, since both pairs of opposite sides of this shape run parallel rather than just one.
