从一个角的顶点出发,把这个角分成两个相等的角的射线叫做这个角的平分线.在初中几何中有关角平分线知识的应用非常广泛,通常用量角器或直尺与圆规来画一个角的平分线,但并不局限于此.全等三角形知识的学习为我们用其它方法画角平分线提供了依据,下面通过三道例题向大家介绍如何利用身边的一些简易工具来画一个角的平分线. Starting from the vertex of a corner, the ray that divides the angle into two equal angles is called the bisector of this angle. The application of the knowledge of the angle bisector in the junior high school geometry is very extensive, usually using a protractor or ruler and compass to draw a The bisector of the angle, but it is not limited to this. The study of the equal triangle knowledge provides the basis for us to use other methods to draw the angle bisector. The following example shows how to draw a corner using some simple tools around us. The bisector.
