通过高中实验教材9B课本,不仅可以学习传统的立体几何的有关知识,而且还可以用空间向量的有关结论去解决立体几何问题.用空间向量可以解决的立体几何问题包括线线平行、线面平行、面面平行等平行与共面问题;点到平面的距离、异面直线的距离、平行平面间的距离等空间距离问题;异 Through the high school experimental textbook 9B textbooks, not only can we learn the traditional knowledge of the three-dimensional geometry, but also can use the relevant conclusions of the space vector to solve the three-dimensional geometric problems. The three-dimensional geometric problems that can be solved with the space vector include the line lines are parallel and the lines are parallel. Parallel and coplanar problems such as parallel surfaces, point-to-plane distances, distances between different straight lines, distances between parallel planes, etc.
