# Geometric drawing

The drawing geometric relates to the geometry and figures characteristics of this discipline . Taking into account that geometry is one of the branches of mathematics, geometric drawings follow its rules. In this way, these drawings are made with flat figures built based on a logical method .

In the simplest geometric drawings, the basic figures of geometry such as circles, squares and triangles tend to be used . Thus, geometric drawings follow the lines and characteristics of these figures and their shapes. The different geometric figures can also be combined to create more complex and elaborate drawings.

These drawings can be used for different purposes and objectives such as creating optical effects, for example. But they can also be used in other fields or professional disciplines such as architecture, for example. Even in the plastic arts, geometric drawings are used as a basis or guide for other drawings.

A geometric drawing uses the shapes and rules of geometry.

In addition, as with other drawings or graphic representations, geometric drawings can be made on different supports . By this we mean that we can make them on paper, cardboard, blackboards or even on a screen. To make these drawings we can use instruments such as a compass, a square or a ruler.

Apart from the instruments and supports used to make these drawings, different techniques are used . Among them we can mention projection systems such as axonometries, perspectives or orthogonal projections. Axonometries are characterized by representing geometric elements or volumes with all their proportions.

Another type of projection system used in geometric drawings is the oblique projection . This type of projection is frequently used to perform scientific calculations concerning the shadows of the elements. Oblique projection is a typical concept of Euclidean geometry that relates projections to the projecting object.
