# Meaning of Two-dimensional

The two-dimensional adjective is used to qualify that which has two dimensions (2D). A body that projects far and wide, for example, has two dimensions. On the other hand, if it also has depth, it is an object with three dimensions (3D) and is called three – dimensional.

In general, the dimensions are defined from the minimum number of coordinates that are needed for the specification of any point in it. In this way, we can affirm that a line is one-dimensional: it reaches a single coordinate to locate a point.

In the case of two-dimensional elements, two coordinates are required to achieve the specification of a point. Polygons, such as squares or triangles, are two-dimensional because, to locate a point, you need to set the longitude and latitude. Following this logic, locating a point in a three-dimensional body (such as a cube) requires knowing three coordinates.

It is common to indicate that our world has four dimensions: three spatial and one temporal. The movements we make are to the left or right, forwards or backwards and downwards or upwards, being able to establish different combinations. In the case of the time dimension, there would be only one direction.

It should be noted that, even on a two-dimensional surface, it is possible to simulate a three-dimensional effect. A sheet of paper is two-dimensional: however, by appealing to perspective, it is possible to draw a cube, giving a feeling of three-dimensionality.

Within the field of electricity we can establish that the term that we are dealing with is also used. Specifically, it is used to refer to the characteristic that a conductive element can have. Thus, it is established that if it is two-dimensional it is because in one of the directions of space it is insulating while in the other two we can determine that it has a higher conductivity.

In addition to everything indicated, it is necessary to determine that there is what is known as a two-dimensional graphic design. This is a discipline that is based on designing and shaping two-dimensional figures for various types of areas. Specifically, for photographs, drawings, paintings, computer images…

Exactly that type of design becomes a great option when it comes to shaping illustrations, logos or fonts, among other elements.

If all the information we have given you is important, even more so to know that the adjective in question is also used within the scope of statistics. In that case, it is used to shape the concepts of two-dimensional statistics or two-dimensional statistical variable.

Two-dimensional statistics is the name given to the discipline that is responsible for analyzing the description of a phenomenon as well as its variations and the changes of two variables. That is, it proceeds to study phenomena in which two variables intervene jointly. Hence, among other things, we proceed to analyze what is the relationship that may exist between the two.
