Problems solved by technology
[0002] In the process of learning, in order to learn better, students will have a full range of tools, so they will prepare a lot of tools, such as rulers, sixty-degree triangles, forty-five-degree triangles, compasses, protractors, etc., a variety of Teaching tools are not easy for teachers to carry, so an easy-to-use drawing ruler is very important
[0003] However, in mathematics teaching at present, teachers generally need to bring a variety of teaching utensils, and various teaching drawing rulers are scattered and placed. The teacher needs to bring all kinds of utensils when teaching. These teaching utensils are not only inconvenient to carry, but also easy to use when teaching. The teacher is in a hurry, which affects the quality of teaching; at the same time, when the teacher explains the principles of graphics, he needs to add a lot of extension lines, which is not very convenient to draw
