解决平面解析几何问题的一般思路是利用坐标法,借助代数推理进行,但对学生的运算能力、恒等变形能力、数形结合能力及综合运用知识的能力要求较高,许多学生由于难以摸清题目的真正意思(本质特性),又惧怕复杂的计算过程,所以往往望而生畏。本文结合平面几何的有关性质、定理巧妙地解决有关解析几何问题。
The general idea of solving the geometric problem of plane analysis is to use coordinate method to make use of algebraic reasoning. However, it has a high requirement on students’ abilities of computing ability, equal deformation ability, number-shape combining ability and comprehensive utilization of knowledge. Many students find it hard to find out The real meaning of the subject (essential characteristics), and fear of complex calculation process, so often daunting. In this paper, the related geometry of planar geometry, theorem cleverly solve the problem of analytical geometry.
