几何学在实际生活用应用非常广泛,与许多学科有着非常密切的联系,所以我对空间立体几何解题的基本方法加以归纳整理,使学生今后的立体几何复习能够更加有效。一、考点分析与学法指导1.立几解答题一般难度不大,特别是引入空间直角坐标系后,计算往往没多大难度,只需记忆几个公式,计算细心,不失误便可得满分。建立空间直角坐标系特别提醒三点:(1)先在几何体中找(或作)出
Geometry has a very wide range of applications in real life and has many links with many disciplines. Therefore, I summarized the basic methods of solving the problem of solid geometry in space and made it more effective for students to review the geometry in the future. First, the test center analysis and learning guidance 1. Several questions to set up a few difficult in general, especially the introduction of space Cartesian coordinate system, the calculation is usually not much difficulty, just remember a few formulas, calculate carefully, without error can get full marks . Cartesian coordinate system to create a special reminder of three points: (1) first geometry (find)
