数形结合法就是根据数学问题的条件和结论之间的内在联系,既分析其代数意义,又揭示其几何意义,使数量关系和图形巧妙地结合起来,寻求解题思路,使问题得到解决.下面举几例供大家参考. The combination method of number and shape is based on the intrinsic relationship between the conditions and conclusions of the mathematical problem, not only analyzing its algebraic significance, but also revealing its geometric meaning, so that the quantitative relationship and graphics can be combined skillfully, and the problem-solving ideas can be sought to solve the problem. Here are some examples for your reference.
