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**Quote:**

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°
