几何问题的解答方法很多,只要能找到解题规律,任何难题都可以迎刃而解,教师在解题教学中要善于引导学生挖掘题目中的隐含条件,从复杂的图形中分解或构造出基本模型图,善于提炼基本几何模型,进行归纳总结.不断寻求新的解题方法,逐步提高自己的解题技能和技巧,以达到举一反三、触类旁通的学习效果.

There are many ways to solve the geometric problems, as long as we can find the law of problem solving, any problem can be solved. Teachers should be good at guiding students to dig the implicit conditions in the problem solving, and decompose or construct the basic model from the complex figure , Good at refining the basic geometric model, to summarize.Continued to find new ways to solve problems, and gradually improve their problem-solving skills and skills, in order to achieve the goal of "learning from the best, bypassing the learning effect.
