以运动的观点来探究几何变化规律的问题称之为运动型问题.这类问题的显著特点是:图形中的某个元素(如点、线段、角等)或整个几何图形按某种运动规律运动,图形的各个元素在运动变化的过程中互相依存.这类试题与一般试题有所区别,可能条件不够完备,也可能结论需要探究,且问题所呈现的形式具有一定的开放性.解答这类问题时,在观察几何图形运动变化的过程中要善于探索并发现一些几何性质、相互关系和规律.学生在解答这类试题时必须具有扎实的基础知识和灵活的解题能力.往往需要综合运用转化思想、数形结
The question of how to explore the law of geometric changes from the point of view of motion is called a motion problem.The salient features of such problems are that some element in the figure (such as point, line segment, corner, etc.) Movement, the various elements of the graphic interdependence in the process of changes in the movement.This type of test questions and general examination questions are different, the conditions may not be complete enough, may also need to explore the conclusions, and the problem presented in the form of a certain openness. Class problems, the geometric changes observed in the process of geometry should be good at exploring and discovering some of the geometric nature, interrelationships and laws.Students in the solution of such questions must have a solid foundation of knowledge and flexibility to solve problems often need to be integrated Use transformation thinking, knot
