动态几何问题是关于几何图形存在动点、动图形等方面的问题。是用运动变化的观点,创设一个由静止的定态到按某一规则运动的动态情景,通过观察、分析、归纳、推理,动中窥定,变中求静,以静制动,从中探求本质、规律和方法,明确图形之间的内在联系。解决这类问题时,要搞清图形的变化过程,正确分析变量与其他量之间的内在联系,建立它们之间的关系;要善于探索动点运动的特点和规律,抓住图形在变化过程中不变的东西;必要时,多作出几 Dynamic Geometry is a question about the existence of moving points and moving figures in geometry. Is to change the point of view of the movement, the creation of a static stationary state to a rule by the dynamic movement of the scene, through the observation, analysis, induction, reasoning, moving glimpse, change static, static braking, to explore Essence, laws and methods, a clear relationship between the graphics. To solve such problems, we must make clear the process of the change of the figure, analyze the internal relations between the variables and other quantities correctly, and establish the relationship between them. We should be good at exploring the characteristics and laws of the movement of the moving points, In the same thing; if necessary, make more
