解三角形问题是高考中必考内容之一,试题中有两类问题学生常常感到很困难,一是与三角形的中线的长度有关的问题以及相似的问题;二是与三角形角平分线有关的问题.因为这些问题与函数、平面几何、平面向量、解析几何等有着密切的联系,它们看似简单,实质上是多种知识的综合.本文将介绍这两类三角形问题的求解策略.一、与三角形一边上的中线等有关的问题 Triangular problem is the college entrance examination will be one of the contents of the test questions, there are two types of problems students often feel very difficult, one with the triangle of the length of the middle of the line and similar issues; the second is the triangle angle bisector-related issues Because these problems are closely related to functions, plane geometry, plane vectors, analytic geometry and so on, they seem simple and essentially a combination of many kinds of knowledge.This paper will introduce the solution strategies of these two types of triangles. The midline on one side of the triangle, and so on
