"Squares"

Three stacked upon three makes nine

and a larger square.

However, stack three rows of

three rectangles on top of one another

and you get a rectangle, and, since

rectangles are generally despised for their unequal

sides, who needs that? Instead, one

could stack three more

rows of three and get a good solid

square. That, however, would require

asymmetry in method (six upon three) and is thus

unacceptable.

It is impossible to stack any number

of upright triangles and produce any recognizable

shape, much less a square.

The same rings true for pentagons,

octagons, and other impractical shapes.

This must the reason squares are

used to line graph paper.
