1, the geometric model can help to better understand various concepts in geometry, such as points, lines, surfaces and bodies. By observing the model, we can feel the meaning and characteristics of the concept more intuitively, so as to better understand the theoretical knowledge of geometry.

2. Geometry needs high spatial imagination, and a geometric model is helpful to improve this ability. By observing the model, we can better understand the spatial structure and characteristics of various geometric shapes, so as to better understand and solve geometric problems.
