立体几何引入空间向量后,可以借助向量工具,使几何问题代数化,降低思维的难度.尤其是在解决一些立体几何探索性问题时,更可以发挥这一优势,以下举例说明.
After the spatial vector is introduced into the three-dimensional geometry, the vector tool can be used to make the geometric problem algebraic and reduce the difficulty of thinking. Especially when solving some stereogeometric exploratory problems, this advantage can be further exerted. The following examples are given.
