动态题是近年来中考的的一个热点问题,以运动的观点探究几何图形的变化规律问题,称之为动态几何问题,以动态几何问题为基架而精心设计的考题,可谓璀璨夺目、精彩四射.其中,面动问题是常见的动态几何问题之一,面动问题就是在一些基本几何图形上,设计一个动面(包括平移和旋转),或由点动、线动形成面动,并对面在运动变化的过程中产生的等量关系、变量关系、图形的特殊状态、图形间的特殊关系等进行研究.下面结合2013
Dynamic problem is a hot spot in the senior high school entrance examination in recent years to explore the changing laws of geometric patterns from the point of view of movement, called dynamic geometric problems, based on dynamic geometric problems and well-designed test questions can be described as dazzling, exciting four Among them, facial motion is one of the common dynamic geometric problems, facial motion problem is that in some basic geometry, the design of a dynamic surface (including translation and rotation), or by the move, the line formed by dynamic action, and Opposite the movement in the process of changing the same amount of relations, the relationship between variables, the special state graphics, the special relationship between graphics and so on.Combination of 2013
