“动点”问题在初中数学中占有重要位置,它的特点是图形中的某个点,按某种规律在运动.由于点的运动往往使题目中的几何图形随之不断变化,使同学们解决这类问题颇感棘手.同学们在解题时,不要被“动”所迷惑,要在动中求静,不妨把动点移动到特殊位置进行分析,也就是先研究几种特殊情况(特例),对你解决一些探求结论型的动点问题会很有帮助,减少了解题的盲目性. The problem of “Moving Point” plays an important role in junior high school mathematics. It is characterized by a certain point in the graph, and is in accordance with a certain law in motion. Because the movement of a point often causes the geometry in the topic to change continuously, so that The students are very troublesome to solve this type of problem. When students solve problems, they should not be confused by “moving”, and they should move to a special position for analysis. That is, they should study first. A special case (special case) will help you solve some of the problem of finding the dynamic point of the conclusion type and reduce the blindness of the problem.
