在初三几何复习中,为了拓宽思路,培养分析问题和解决问题的能力,常常要采用“一题多解”来进行思维训练,对于“一题多解”的问题,首先要仔细审题,认真分析,打开思路。而关键在于根据已知条件添加辅助线,从不同的角度去寻找解题的途径,从而获得异曲同工的效果。 In the third grade geometry review, in order to broaden the train of thought and cultivate the ability to analyze problems and solve problems, it is often necessary to use “multiple solutions to one problem” to carry out thinking training. For the “multiple solutions to one problem” problem, we must first carefully examine the issues and earnestly Analysis, open ideas. The key lies in adding auxiliary lines according to known conditions and finding ways to solve problems from different perspectives, so as to obtain the same effect.
