السؤال 36

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.

Rhombus, because its four sides are equal.الإجابة الصحيحة
Rectangle, because it has four right angles and equal opposite sides.الإجابة الصحيحة
Square, and no other name, because quadrilateral names never overlap.
Trapezoid, because only one pair of its sides is parallel.

الشرح

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.
