几何题目中的面积问题,往往是通过等积定理和面积比定理来解的．而对于一些非面积问题也可以借助于面积来解,即所谓面积方法,基本上是利用面积公式,将图形中适当的面积关系转化为等式,并在此基础上经过计算导出结论．下面以中考题为例来说明． The area problem in geometric problems is often solved by the equal product theorem and area ratio theorem. For some non-area problems can also be solved with the aid of area, the so-called area method is basically the use of area formulas, the appropriate area relationship in the graph is converted into equations, and on this basis, the conclusion is derived through calculations. The following examples take the exam questions as an example.
