以几何图形为载体,动点(双质点或多个质点)在几何图形上按某种规律以一定速度运动的问题,沟通了相似与几何图形性质之间的密切关系,解决此类问题我们要充分发挥数形结合的指导思想,以时间为未知数,借助路程与时间、速度的关系,表示出相关线段的长度,然后根据相似三角形的性质得到比例式并作为相等关系来布列方程,方可获得问
Geometry as a carrier, the moving point (double or multiple particles) on the geometry of the law by a certain rate of motion at a certain speed, communication between the similarities and the nature of the relationship between geometric properties, we need to solve such problems Give full play to the guiding ideology of combination of numbers and forms, formulate the equations according to the properties of similar triangles and equate them as equal relations, taking the time as an unknown number and expressing the length of the relevant line segment by the relationship between the distance and time and speed Get asked
