角的平分线在解几何题中有着重要的作用.如果已知条件中涉及到角的平分线,我们则可应用其性质作为解题的途径,把问题化难为易,迅速求解.下面举例说明.一、以角平分线为轴翻折构造全等三角形
The bisector of the angle plays an important role in solving the problem of geometry. If the known conditions involve the bisector of the angle, we can apply its properties as a way to solve the problem and solve the problem as quickly as possible. First, the angle bisector as the shaft fold structure congruent triangle
