立体几何在传统解法的基础上,引入空间向量的知识,丰富与拓展了研究手段.用向量解题有两种方法可供选择,一种是用向量的代数式运算,一种是用向量的坐标运算.空间向量在处理空间问题时具有相当的优越性,可以说向量是代数与几何之间的一座天然的“桥梁”.本节知识主要就是培养用向量工具将几何问题代数化的转化能力.
On the basis of the traditional solution, the three-dimensional geometry introduces the knowledge of the space vector and enriches and expands the research methods. There are two methods to solve the problem with the vector. One is the algebraic operation of the vector, and the other is the coordinate of the vector. Operations. Space vectors have considerable advantages when dealing with space problems. It can be said that vectors are a natural “bridge” between algebra and geometry. This section of knowledge is mainly about the transformation of geometric problems with algebraic transformation using vector tools. ability.
