质点运动型问题就是在三角形、四边形等一些几何图形上,设计一个或几个动点,并对这些点在运动变化的过程中相伴随着的等量关系、变量关系、图形的特殊状态、图形间的特殊关系等进行研究考察,质点运动型问题常常集几何、代数知识于一体,数形结合,有较强的综合性.解决质点运动型问题需要用运动与变化的眼光去观察和研究图形,把握动点运动与变化的全过程看,抓住其中的等量关系和变量关系,并特别关注一些不变量、不变关系或特殊关系,尽管一些试题大多属于静态的知识和方
The problem of particle motions is to design one or more moving points on some geometric shapes, such as triangles and quadrilaterals, and to determine the relationship between variables such as the relationship of variables, the special state of the graph, the shape of the graph Between the special relationship between the study and study, particle sports problems often set geometry, algebraic knowledge in one, the combination of a few figures, there is a strong comprehensive solution to particle sports problems need to use movement and change of vision to observe and study graphics Grasp the whole process of motion and change of moving point, grasp the relation of equal relation and variable, pay special attention to some invariants, invariant relation or special relationship, although some questions mostly belong to static knowledge and method
