1引言几何学是研究现实世界中物体的形状、大小与位置关系的数学学科.立体几何(Solid geometry)一般是指三维欧氏空间的几何的传统名称,多作为平面几何的后续课程.高中数学立体几何必修课程的基本要求是认识空间图形,培养和发展学生的几何直觉、运用图形语言进行交流的能力、空间想象能力 1 Introduction Geometry is a mathematical discipline that studies the shape, size and position of objects in the real world Solid geometry generally refers to the traditional names of geometries in 3D Euclidean space and is often used as a follow-up course to plane geometry. The basic requirements of the three-dimensional geometry compulsory course is to recognize the space graphics, to develop and develop students’ geometric intuition, the ability to communicate in the graphic language, spatial imagination
