Δύο διαστατικός χώρος Ορισμός

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.
