1. Draw a center point on the paper with a pencil as the center of the circle. Make sure the position of this point is accurate, because the size and shape of the circle depend on the position of this point.
2. Use compasses, with one foot on the center of the circle and the other foot on the paper. Adjust the scale of the compass to be equal to the radius of the circle you want to draw. For example, if you want to draw a circle with a diameter of 5 cm, you need to set the scale of the compass to 2.5 cm.
3. Keep the other foot of the compass still and rotate the handle of the compass along the paper, so that one foot of the compass draws a circle on the paper. This process may require some practice to ensure that the circle you draw is a perfect circle.
4. Check whether the circle you drew is satisfactory. If you are not satisfied, you can erase the wrong part with an eraser and redraw it. Once you are satisfied with your circular pattern, you can color it with colored pencils or watercolor pigments to enhance its aesthetic feeling. Finally, you can add some decorative elements around the circular pattern, such as patterns, lines or words, to make it more exquisite and unique.
The function of compass
Compass is a common drawing tool, which is mainly used for drawing circles and measuring lengths. It consists of two feet, one is a sharp needle tip, and the other is a pencil or nib that can be fixed on paper.
2. Using compasses can draw a perfect circle conveniently. First, put one foot of the compass on the paper as the center of the circle and the other foot on the paper as the starting point of the radius. Then, rotate the handle of the compass so that one foot of the compass draws a circle along the paper. You can draw circles of different sizes by adjusting the scale of the compass.
Besides drawing a circle, compasses can also be used to measure the length. Put one foot of the compass on the starting point and the other foot on the end point, and then read the scale on the compass to get the distance between the two points. This method is more accurate than the traditional ruler, because the two feet of the compass always keep the same distance, avoiding human error.
In addition, compasses can also be used to draw other shapes, such as squares and triangles. By combining different geometric figures, you can create various complex patterns and designs.
