Stereo (regular): cube, cuboid, cylinder, prism, frustum, frustum, cone, pyramid, sphere (less common).
Application of geometric figures;
1. Geometry is widely used, and it is needed in design, painting creation and mathematical research.
2. Mathematical definitions, theorems, etc. It is very abstract in mathematical language, and theorems are difficult to remember, so it is an important link in teaching to help students remember and define theorems. If geometric figures and numbers are properly combined in teaching, students can deepen their understanding of intuitive figures and master their theorems.
