近年来,以几何图形的运动为载体,求几何图形在运动过程中某点所经过的路线长度的题目经常在中考试卷中出现.解答这类试题,首先要搞清图形在运动过程中某点所经过的各段路径,然后求出各段路径的长度,最后求出总的路径长度.现采撷几例作解析,供大家参考. In recent years, the geometry of the movement as a carrier, geometry and geometry in the course of the course of the route length of the problem often appear in the examination paper.To answer such questions, we must first find out the graphics in the movement of a point After the passage of the various sections, and then find out the length of each section of the path, and finally find the total length of the path is now picking a few examples for analysis, for your reference.
