A
square is one of the basic shapes of
geometry. A two-dimensional figure with four verticies.
In arithmetics
? and
algebra, the
square of an entity
x is the result of multiplying it with itself. This is the same as computing the surface area of a geometric square of size
x, and the same as
x raised to the power of two:
x2 =
x *
x
In
architecture, a
square means an intentional open space in a
city. See [Red Square]
? and [Tien Anmen]
?.
In carpentry
?, a square is a tool used to establish right angles between boards. Paradoxically, its appearance resembles a
triangle.
