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.
