What if it's a square? Is the assumption that every 'square' is a rectangle?
Hi,
Yes, every square is a rectangle because it fulfills all requirements of a rectangle like opposite sides equal, diagonal equal and all angles are 90...
It is just that additionally a square has not only OPP sides but all sides are equal..
And the diag are not only equal and bisect each other but also cut each other at 90..
Thus all square are rectangle but all rectangle need not be square...
Hope it helps
what is the difference?

Thought this was a good question; really tested my visualization. (Please don't think harder just because I said that...)
The question has quite ambiguous wording...
Anyway, check the diagram below:
