Description

Technical Field

[0002] In the process of teaching mathematics to derive mathematical formulas, it is necessary to draw curve graphs corresponding to the mathematical formulas, as well as the shapes of the figures, in order to better learn the properties of the figures. In the study of circles, it is necessary to understand the basic concepts of circles by drawing circles, such as the center, radius, diameter, etc., as well as related geometric theorems and formulas.

[0003] In the existing technology, a compass is usually used to draw a circle. However, when drawing a circle with a compass, the position of the center of the circle of the fixed foot is easily offset, the radius distance between the two feet of the compass cannot be directly measured, and the distance between the two feet is easily changed due to external forces such as hand shaking, which changes the radius of the circle and affects the drawing quality of the circle. At the same time, when drawing an arc with a compass, it is not easy to accurately control the angle of the arc, which affects the convenience of the drawing operation. Utility Model Content
