纵观2004年全国各地高考立几综合题,求空间距离、空间角及证明空间平行垂直关系是立体几何题盛行不衰的主题.而利用向量法处理这些问题具有很强的操作性、稳定性.下面举例谈谈向量法求解2004年高考立体几何试题的类型及解题方法.1　利用向量法证明平行问题空间图形的平行关 Throughout the 2004 national college entrance examination set a few comprehensive questions, seeking space distance, space angle and proof of space parallel vertical relationship is the subject of three-dimensional geometric problems prevail.While using vector method to deal with these problems has strong operability, stability The following gives an example to talk about the vector method to solve the type of the college entrance examination in 2004 and the method of solving problems.1 The use of vector method to prove that the parallel problem of spatial graphics parallel off
