In [[mathematics]], a '''plane''' is any flat, two-[[dimensional]] [[surface]]. A plane is the two dimensional analogue of a [http://en.wikipedia.org/wiki/Point_(geometry) point] (zero-dimensions), a [http://en.wikipedia.org/wiki/Line_(geometry) line] (one-dimension) and a [[space]] (three-dimensions). Planes can arise as subspaces of some higher dimensional space, as with the walls of a room, or they may enjoy an independent [[existence]] in their own right, as in the setting of [http://en.wikipedia.org/wiki/Euclidean_geometry Euclidean geometry].
