在学习与三角形有关的角时,同学们会遇到许多求角的问题,其中有些题目看似简单,却很难入手,或者是由于思考不全而造成漏解,怎么办?本文将谈谈一些数学思想方法在这类题目中的运用,希望对同学们图1解题有所帮助.一、整体思想例1如图1,若点P为∠B、∠C的角平分线的交点,求∠BPC-2 When learning the angles related to the triangles, students will encounter many problems with seeking angles. Some of these problems may seem simple, but they are difficult to get started, or they may be due to incomplete thinking. What should we do? This article will talk about some The use of mathematics thinking methods in such topics hopes to help the students solve problems in Figure 1. First, the overall thinking example 1 is shown in Figure 1. If the point P is the intersection of the angle bisector of ∠B, ∠C, find ∠BPC-2
