A geometric drawing is a flat figure.
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 "draw".
-Geometric, for its part, derives from Greek. Exactly it is the result of the sum of three components of said language: "geo", which is synonymous with "earth"; the noun "metron", which means "measurement", and the suffix "-ico", which is used to indicate "relative to".
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. This time we will focus on geometric drawings .
Geometric is that linked to geometry , which is the specialty of mathematics oriented to the analysis of the 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 graphs are carried out using plane figures , which are constructed 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 layouts that play an essential role in geometric drawing, we can highlight the point, the line, the straight line, the curved line, the semi-straight line, the segment... In the same way, it is established that in order to achieve a good geometric drawing, it becomes 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, angle protractor, scale meter and the corresponding plates.
Within education, it is very common for students, in different courses and levels, to learn to make geometric drawings. And this will help them not only 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 these are artistic drawings that seek to generate certain optical effects. In this case, the aesthetic result is privileged. There are also geometric drawings that professionals develop within the framework of 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 color through geometric drawings.
There are various ways to make these drawings. They can be done on paper, cardboard or another flat surface, by hand and with the help of an instrument (a ruler, a square, a compass or another), for example. Another possibility is to develop them with some computer program ( software ).
