[0002] In junior high school mathematics teaching, it is necessary to explain the relationship between projected views to students. Simply using textbooks cannot give students a deep understanding of the knowledge points, especially when junior high school students first come into contact with projected views, their comprehension ability is even more limited
In order to allow students to learn the teaching content intuitively and visually, and improve students' enthusiasm for learning, the existing teaching aids require teachers to manually adjust the position of the model, which reduces the teacher's teaching efficiency
