立体几何第一章“直线与平面”是立体几何的核心内容,学好了这一章就为下一章的学习打好了良好的基础。而这一章的直线与直线、直线与平面、平面与平面的平行与垂直关系又是这一章的重点。高考中往往是以立体几何第二章的内容为依托,实际上考查的是第一章的知识。因而,在复习中要抓住要点,把基本知识、基本方法有机地串联起来,使学生领会、掌握立体几何解题的基本技能。具体来说,在复习中要把握好以下三条原则:一、四条公理是推理的基础推理溯源,有时须追溯到人们公认的基本事
The first chapter of the three-dimensional geometry “straight line and plane ” is the core of the three-dimensional geometry, learn this chapter for the next chapter to learn lay a good foundation. And this chapter of the line and straight, straight and plane, plane and plane parallel and vertical relationship is the focus of this chapter. College entrance examination is often based on the content of the second chapter of the geometric geometry, in fact, is the first chapter of knowledge. Therefore, in the review, we should seize the key points, put the basic knowledge and basic methods organically in series so as to make the students understand and master the basic skills of solving the problem of solid geometry. Specifically, the following three principles should be grasped in the review: 1. The four axioms are the source of the basic reasoning for reasoning, and sometimes they must be traced back to the accepted basic issues
