在现行中学数学教学大纲中,关于立体几何课的内容,规定得不是很多的。而且都是最简单的、当然也是最基础的立体几何的理论知识。虽然如此,对于初学立体几何的高中一年级的学生来说,由于他们一般的知识和能力的基础与学习立体几何之所需,多少 In the current middle school mathematics syllabus, there are not many provisions on the contents of the three-dimensional geometry lesson. And they are the simplest and, of course, the most basic theoretical knowledge of solid geometry. However, for first-year high school students who are novice in stereo geometry, due to their basic knowledge and ability and the need to learn solid geometry,
