众所周知 ,图形在数学解题中起到很重要的作用 ,有些几何问题在没有图形辅助的情况下 ,解题思维几乎无法开展 .图形在解题中都是起些什么作用 ?华罗庚先生说“数无形时少直觉” ,其实 ,图形给解题者一个直观的关于问题中基本元素间的位置关系图式 ,使解题者能够较容易地将当前 It is well-known that graphs play an important role in solving problems in mathematics. Some geometric problems can hardly be solved in the absence of graphical aids. What role does graphics play in solving problems? Mr. Hua Lugeng said: “Intangible, intangible, and less intuitive”, in fact, the graph gives the solver an intuitive positional relationship diagram between the basic elements of the problem so that the solver can more easily
