有些几何知识应用题与运动有关,如两个物体在环形跑道上运动,那就是相遇问题或追及问题。通常求几何图形的面积或周长是静态的,但是也有些是运动着的,解决这类问题,要认真分析运动着的物体所经过的路线,综合运用所学知识,这样才能找到解 Some questions about geometry apply to exercise, such as two objects moving around a circular runway, which is to meet or catch up with the problem. Generally, the area or perimeter of the geometric figure is static, but some are also moving. To solve such problems, we must carefully analyze the route that the moving body passes and apply the knowledge synthetically so as to find the solution
