What about square, can it be accepted as rectangle?
if yes than C
If no than E
I encountered a similar question and was wondering about the same thing!! Any quant experts?????
No, a square is a square and a rectangle is a rectangle. Both are special forms of parallelograms with their own individual properties. For instance, the diagonals of a square intersect at right angles, but the diagonals of a rectangle don't.
ywilfred, sorry but I must disagree.
A square is at the same time:
> a rectangle
> a paralellogram
> a quadrilateral
A square is a special rectangle with a right angle at the intersection of its diagonals
... or... with same length of edges
All properties from a rectangle are verified by a square, making it a rectangle... Indeed, we could represent the figures groups and sub-groups such as my attached picture Some more references: http://www.mathopenref.com/square.html
A square can be thought of as a special case of other quadrilaterals, for example
* a rectangle but with opposite sides equal
* a parallelogram but with opposite sides equal and the angles all 90°
* a rhombus but with angles all 90°
