角的平分线1、角平分线：把一个角平均分为两个相同的角的射线叫该角的平分线;
2、角平分线的性质定理：角平分线上的点到角的两边的距离相等：①平分线上的点;②点到边的距离;
3、角平分线的判定定理：角的内部到角的两边的距离相等的点在角平分线上
4、方法规律
(1)有角平分线，通常向角两边引垂线。
(2)证明点在角的平分线上，关键是要证明这个点到角两边的距离相等，即证明线段相等。常用方法有：使用全等三角形，角平分线的性质和利用面积相等，但特别要注意点到角两边的距离。
(3)注意：证题时可直接应用角平分线性质定理和判定定理，不必去找全等三角形。
怎样学好初中数学
1、课后分析看例题??
课堂上例题弄懂了，并不说明你具备了解题能力和知识迁移能力。课后还需要从一个新的角度重新审视、分析例题。由于新的知识的掌握、知识面的扩展以及老师的引导、点拨，再看例题时则对难点有了不同的认识，进入了更高的层次。对题中基础知识的运用，分析、推理方法的选择都会有更深的理解。如果课后不看例题思维就会停留在一个浅层次，无法完成由浅入深，由表及里的转化过程。?? ?
2、作业推理识例题??
做练习是运用知识解决问题提高能力的最重要最有效的方法，也是学好数学的关键。做作业时首先要识别例题，即这道题属于本章节所讲例题的哪一类型;其次要回忆上课老师是如何解题的，再分析有几种解题方法，最后明确哪一种方法最简便。如果识记不清或对以前学过的例题产生了遗忘，要不惜时间去翻阅、分析、记忆。
