巧用“面积法”解几何题

Ingeniously Solve Geometrical Problems with "Area Method"

几何问题解法种种,方法得当,证法就直接、简便;方法利用得好,证法就巧妙、优美。以教学例子为鉴,“面积法”真是解决某些几何问题的良药。

There are lots of ways to solve a geometrical problem. If the way is proper, the solvation will be simple and direct; if the way is good, the solvation will be elever and beautiful. With a teaching case as an example to show the 'area method' is really a good way to solve certain geometrical problems.
