立体几何初步的学习重点是逐步形成空间想象能力,即以常见的空间几何体为载体,进行识图与画图的训练,在直观感知的基础上,认识空间中一般的点、线、面之间的位置关系;通过对空间图形的观察、实验、操作和思辨,了解平行、垂直关系 The initial focus of the study of solid geometry is the gradual formation of spatial imagination capabilities, that is, the common space geometry as a carrier for knowledge and drawing training, intuitive perception, based on the understanding of the space between the general point, line, surface Location relationship; through the observation of spatial graphics, experiments, operations and speculation, to understand the parallel, vertical relationship
