Drawing triangles with a compass and a rule is shown in the figure.
An equilateral triangle with side a is drawn in this way, that we measure segment AB on the straight line, equal to the side of a triangle. From points A and B, radius equal to the segment AB, …
We know, that the angle is part of the plane, which is bounded by two rays coming from one point, called the vertex of the angle. Any angle can be divided into halves. To do this, we make an arc of any radius from point A, which …
If you want to divide the segment AB into two halves, arcs with a radius greater than half of the segment AB should be drawn from points A and B. We mark the intersections of the arcs with points C and D. By connecting them together, we get the intersection of the line connecting with …
A line perpendicular to a given straight line can be drawn in two ways. The first is to draw a perpendicular from a specific point lying on the line p, second – from the point outside the straight line p. We will use a compass to plot both constructions …
It is often necessary to draw grids for different graphs, sketches, subtitles, decorative projects etc.. The grid can consist of square grids made of drawing vertical and horizontal lines at equal intervals (Figure A) or also …
The easiest way to draw horizontal lines is with the help of a fence (Figure A), by guiding the pencil or graphion close to the upper edge of the ruler and keeping it constantly at the same angle of inclination to the plane of the paper, without tilting it …
A zero caliper is used to draw circles with small radii. In some drawings, these small circles mark the main points or intersection points, circles and rays.
Figure a shows how to use it …
When drawing basic geometric figures, we most often use a drawing board, a fence and right triangles with angles of 45 °, 60 ° and 30 °.
The figure shows the most common ways of drawing with sets of triangles using a drawing board and a fence.
Drawing paper or …
Let's start the initial drawing exercises with the simplest geometric element, what is the point, and let us illustrate its position on any surface with a few examples. Let's think about it, how to arrange one, two, three and many points, that they constitute ordered systems. Point …
