在初中几何题中,经常会碰到一些和垂线段有关的问题,这就要求学生要懂得利用特殊位置法猜测垂线段之间的数量关系,善于构造三角形并利用三角形面积之间的数量关系证明结论。
In junior middle school geometry problems, we often encounter some problems related to vertical segments, which require students to know how to guess the quantitative relationship between vertical segments by using the special position method. They are good at constructing triangles and using the quantitative relationship between the triangular areas in conclusion.
