在高中数学教材第二册下(B)中引入了空间向量,用向量知识来研究空间问题是教材的主题思想,使我们解决立体几何问题有了新理念、新方法.下面举例谈谈用空间向量证明空间线面平行与垂直问题.
In the second volume of high school mathematics textbooks (B), the space vector is introduced. The use of vector knowledge to study spatial problems is the theme of the textbooks. It enables us to solve the three-dimensional geometric problems with new ideas and new methods. The following example uses space. Vector Proof Space Lines Parallel and Vertical Problems.
