Two Dimensional Space Definition
Two dimensional space otherwise referred to as bi-dimensional space is a geometric setting in which two values (called parameters) are required to determine the position of an element (a point). The set ℝ2 of pairs of real numbers with appropriate structure often serves as the canonical example of a two dimensional Euclidean space. For a generalization of the concept, see dimension. Two-dimensional space can be seen as a projection of the physical universe onto a plane. Usually, it is thought of as a Euclidean space and the two dimensions are called length and width.
