2 Dimensional Geometry

The Point

            A point is an imaginary object - a single, implicitly spherical object that defines a location. (see diagram 1). A point is theoretical - a sphere of radius zero.

The Plane

            A plane is defined in mathematics as the surface created by the intersection of two lines. While not complete, this definition leads one to imagine a line that sweeps out a surface like one unrolls a carpet. (see diagram 2).
