| Abstract: | The spin altematidon is a found-ammental contracting one. According to its basic character, we can changethe condition of a problem and approach a correct conclusion by inferance, and solve the problem. With 6 examples andfrom 3 aspects the article expounds the advantage and good effect of spin alternation method in solving problems in planegeometry. |
