解题可以巩固基础知识,掌握解题的基本技能,同时还可以促进学生数学思维和素养的发展.然而当一题多解让我们眼花缭乱,叹为观止的时候,也希望用一个方法解决一类题,学习有章可循的解题通法.比如北京中考2012-2015连续四年的几何综合题,每题都可以展开一题多解,感受数学的好玩和神奇之时,我不禁想问:"这四道题是否可以用一种方法
Problem solving can consolidate the basic knowledge, master the basic skills of problem solving, but also can promote the development of students’ mathematical thinking and accomplishment.However, when more than one solution gives us a dazzling, breathtaking, but also hope that a method to solve a class of questions, Such as Beijing exam 2012-2015 for four consecutive years of geometric synthesis questions, each question can be more than one problem, feel the fun and magic of mathematics, I can not help but want to ask: Whether these four questions can be used in a way
