PLANE

Plane

In mathematics, a plane is a flat, two-dimensional surface. A plane is the two dimensional analogue of a point, a line and a solid . 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 Euclidean geometry.
