A four sided shape with opposite sides that are parallel and of equal length.

Why can it not be a square?

Answer is rhombus

Many thanks

A square is a special case of a rhombus, which just happens to have four 90 degree angles rather than 2 pairs of different angles.

I suppose the only way to look at it, given the answer, is

"A four added shape with opposite sides that are parallel and of equal length. "

that the opposite sides are both, parallel and equal, implying that they are not all equal but just the oposite sides. I repeat this is an explanation to fit the answer.

I'm glad this question got posted because DD2 wrote square too and I struggled to give her a rationale as to why it was a rhombus and what to logic to apply, should this type of question come up again :roll: DD1 has shouted through to me that she would have answered "rhombus" - her reason being that square is too obvious :roll: :lol:
