专题综述动态几何问题是从运动的视角探究几何图形局部规律的问题.图形中局部元素的运动。在带动其他几何元素变化的同时。往往蕴藏着耐人寻味的不变性.因这类问题综合性强,考查角度广,难度较大,深受命题专家的青睐,现已频繁出现在各省市中考压轴题中.从运动对象的角度上看,动态几何问题可以分为三类:点动型、线动型以及面动型.解题策略:(1)通过画图、拆解图形等方式梳理条件。理清条件与条件之间的关系.(2)分析运动过程,把面的运动转化成线
Thematic Summary The dynamic geometry problem is to investigate the problem of the local law of geometry from the perspective of motion. While driving the changes in other geometric elements at the same time. Often contain intriguing invariance.For such problems comprehensive, test wide angle, more difficult, favored by the proposition experts, now has frequently appeared in the provinces and cities in the test pressure axis problem .From the perspective of the object of movement , Dynamic geometric problems can be divided into three categories: jogging, linear and surface dynamic type. Problem-solving strategies: (1) by drawing, disassembling graphics and other ways to sort out the conditions. To clarify the relationship between conditions and conditions. (2) Analysis of the process of movement, the surface movement into a line
