Compasses are used to draw circles or strings in mathematics and drawing. They are often used for drawing with rulers. The compass is usually made of metal, including two parts connected by a hinge, which can be adjusted. Students will often use compasses in their studies. The following introduces the correct use of compasses. Let everyone know more about student supplies.
How to use compass
1. Use a ruler to measure the distance between the feet of the compass as the radius.
2. Fix the end with the needle in one place as the center of the circle.
3. Rotate the end with the pencil one turn.
Precautions
1. The height between the feet of the compass should be the same.
2. In the process of drawing a circle, the compass should be slightly inclined by about 30 degrees to make the line of the drawn circle smooth.
3. The end with the needle (ie the center of the circle) cannot be moved during the process of drawing a circle.
4. The distance between two feet (ie radius) cannot be changed during the process of drawing a circle.
The above is how to use the compass, but there are some precautions when using the compass. For example, the compass will be better drawn on thicker paper. The needle length of the compass should be the same as the length of the pen tip.
