The protractor is provided with inner and outer scale marks and numerical values in opposite directions, and two readings appear during angle measurement, so that the difficulty is increased for beginners, and errors are easily caused. On the other hand, when the protractor is used for drawing an angle with a specified degree, a ray needs to be drawn firstly, then the center point of the protractor is superposed with the end point of the ray, so that a 0-degree scale line is superposed with the ray, then a point is drawn on the outermost periphery of the protractor corresponding to the corresponding scale line, and then an angle ray is formed by the two points through the points with the corresponding angles by taking the end point of the ray as a reference, so that the steps are complex and are not beneficial to being mastered by students. When the triangular ruler is used for drawing the vertical line and the rectangle, the drawn vertical line and the drawn rectangle are not standard due to right-angle abrasion of the triangular ruler, and the drawing difficulty is increased. When drawing parallel lines, need two rulers cooperation, the line limit coincide earlier, then two rulers are close to through translation ruler, drawing the straight line, draw two parallel lines, but difficult operation, the easy condition that appears drawing askew parallel lines because of the displacement of location chi.
