以立几知识为载体,以空间向量为工具,以考查空间线、面位置关系的论证和空间距离、空间角有关公式及其应用为目标,是近年高考的重要内容,预计这也是2005年高考的热点试题,下面例说其常考题型,以展示构建空间坐标系,通过向量的坐标运算,解决立几问题的思想方法和思维过程,希 Taking several knowledge as the carrier and using space vectors as tools, it is an important content of the college entrance examination in recent years to examine the argumentation of space lines and surface position relationships, and the distance distance and space angle formulae and their applications. It is expected that this is also the 2005 college entrance examination. The hottest questions, the following examples of their examination questions, in order to demonstrate the construction of space coordinate system, through the coordinate calculation of the vector, to solve the problem of thinking and thinking process, the process of thinking
