A rectangle is a parallelogram whose sides intersect at 90° angles. Now, since a rectangle is a parallelogram, its opposite sides must be congruent.
A square is also a parallelogram whose sides intersect at 90° angles. Therefore, like a rectangle its opposite sides are congruent. However, a square has an added feature. It is also a rhombus. Therefore, all of its sides are congruent.
A rectangle is a square when both pairs of opposite sides are the same length. This means that a square is a specialized case of the rectangle and is indeed a rectangle.http://www.mathwarehouse.com/geometry/q ... tangle.php
You're wrong on this one Scar. A square is a rectangle. I specifically remember learning it in geometry class, and it's been a lot less time between when I took it and when you took it. Sorry, I had to point that out...
