[0003] Geometry teaching molds are physical models or tools used to assist in geometry teaching, aiming to help students better understand and grasp geometric concepts. These molds help students intuitively see the properties of geometric figures, such as shape, size, angle, and the relationships between them.

[0004] Currently, existing geometric molds cannot be used for teaching demonstrations in a three-dimensional and intuitive manner, which restricts hands-on operation and sensory cognitive experience. This largely leads to the problem that students still have only a superficial understanding after learning and cannot apply what they have learned to other situations and integrate the knowledge. Therefore, the development of more advanced and convenient three-dimensional display geometric teaching molds has become an urgent problem to be solved. Utility Model Content
