The concept of figure It has several uses. In this opportunity, we will focus on the idea of a figure that is used in geometry.
A geometric figure it is constituted from the closing of a space with surfaces or lines . Also called a figure is the representation that is made of a geometric element in space or in a plane.
It is important to note that geometric figures are the object of study of this branch of mathematics , whose purpose is to analyze the magnitudes and properties of these figures.
It can be said that a geometric figure is a set that has the points as elements The lines that enclose the points represent the limits of said set and separate it from space.
A point In fact, it is a geometric figure in itself. It is a dimensionless element: it has no dimensions. The straight and the curve , meanwhile, they are linear geometric figures since they have a single dimension.
Among the two-dimensional geometric figures (flat) we find the polygons , Like the squares and the triangles . On the other hand, the name given to three-dimensional geometric figures is geometric bodies . Polyhedra like pyramids and the prisms They are bodies of this type.
It should be noted that points are fundamental entities of geometry. With the geometric figures of a dimension Two-dimensional geometric figures can be produced while, through various transformations, it is possible to obtain three-dimensional or even more dimensional geometric figures.
For example: a segment It is a linear geometric figure formed by a finite amount of points. With the union of four segments, we can produce a rectangle (a two-dimensional geometric figure).
The geometric figures have a large number of applications in the real world, despite being an abstract concept in that they arose from the observation that the human being made of the nature around it. In other words, we cannot find on our planet a cube, a circle or a point, but with these and other figures we represent parts of real objects to be able to understand them more easily.
And this brings us to one of the most popular uses of the geometric figure as a concept: 3D design. Today, almost all content in the entertainment world is made with the help of tools digital, and three-dimensional animations appear more frequently than the general public perceives. It is not necessary to be in front of the most recent film of Pixar to see on the big screen various three-dimensional models, and most of them are created from simple geometric figures.
In a 3D design tool, we usually have at our disposal several geometric figures, such as a plane, a cube and a sphere, which we can use as a basis for the elaboration of objects of diverse complexity, covering a range almost as wide as Let us imagination. Both a chair and a human being, a leafy tree, a colorful meadow and a waterfall depart from these figures before reaching the level of realism that we are accustomed to seeing in the cinema and the video game .
Taking a geometric figure as simple as a plane it is possible to create more faces from its sides and then rotate them and get a three-dimensional object; If we repeat these steps and combine them with other types of deformation, in a short time we will obtain results that will reflect the flat from which we start. As a curious fact, in video games, regardless of the graphic complexity of an object, basic geometric figures are often used to define its limits and prevent it from crossing the stage.
