Flat


Plane comes from the Latin Planus. The Royal Spanish Academy defines this word as flat, smooth, without relief. In geometry, this term is widely used to refer to a schematic representation, in two dimensions and at a certain scale, of a piece of land, a population, a machine, a construction, etc.

In addition, a plane is the ideal entity that only has two dimensions, and contains infinite points and lines; It is one of the fundamental geometric entities along with the point and the line. It can only be defined or described in relation to other similar geometric elements.

It is usually described based on the characteristic postulates, which determine the relationships between the fundamental geometric entities.

When we talk about a plane, we are referring to the geometric surface that does not have volume (that is, it is only two-dimensional) and that has an infinite number of lines and points that cross it from one side to the other.

However, when the term is used in the plural, we are talking about that material that is made as a graphic representation of surfaces of different types. Plans are especially used in engineering, architecture and design since they are used to diagram other surfaces that are regularly three-dimensional on a flat surface.

Plans are especially used in engineering, architecture and design since they are used to diagram other surfaces that are regularly three-dimensional on a flat surface. An example of this is the plan of a city, which is a graphic and scale representation of a piece of land, a population or the floor plan of a building.
