To know the meaning of the term geometric drawing, it is necessary, first of all, to discover the etymological origin of the two words that give it shape:

-Drawing comes from French, exactly from the verb “déboissier”, which can be translated as “to draw”.

-Geometric, on the other hand, derives from the Greek. It is exactly the result of the sum of three components of said language: “geo”, which is synonymous with “earth”; the noun “metron”, which means “measure”, and the suffix “-ico”, which is used to indicate “related to”.

A geometric drawing is a plane figure.

What is a geometric drawing

There are multiple types of drawings (strokes or delineations that allow a figure to be represented): there are artistic drawings , technical drawings, architectural drawings , mechanical drawings and electrical drawings, among others. In this opportunity we will focus on geometric drawings.

Geometric is that related to geometry, which is the specialty of mathematics oriented to the analysis of magnitudes and properties of figures in space or on a plane. A geometric drawing, therefore, is one that is made following the rules of this discipline.

These graphics are carried out using flat figures, which are built following a logical method. In general, certain basic layouts (triangles, circles, squares, etc.) are used to develop the drawings.

The creation of a geometric drawing can be facilitated by using certain tools or instruments.

How to create these figures

Among the basic paths that play an essential role in geometric drawing, we can highlight the point, the line, the straight line, the curved line, the ray, the segment… In the same way, it is established that in order to achieve a good geometric drawing it is necessary and essential to master the bisector of an angle, the perpendicular bisector of a segment, the sum of angles, the perpendicular line through a point or the circumference, among others.

To undertake geometric drawings it is necessary to have tools such as pencils, square and bevel, compass, protractor, scale meter and the corresponding sheets.

Within education, it is very common for students, in different courses and levels, to learn to make geometric drawings. And it is that this will help them not only to improve their skills and knowledge in the plastic area but also in other disciplines such as mathematics or technology, for example.

Usefulness of a geometric drawing

Geometric drawings can be used for different purposes. Sometimes they are artistic drawings that seek to generate certain optical effects. In this case, the aesthetic result is privileged. There are also geometric drawings that are developed by professionals within other kinds of drawings (such as an architect using a rectangle to represent a room on a plan). Children, on the other hand, can learn to recognize the various figures of geometry and even to color through the geometric drawings.

There are several ways to make these drawings. They can be done on paper, cardboard or another flat surface, by hand and with the help of some instrument (a ruler, a square, a compass or another), for example. Another possibility is to develop them with some computer program (software).
