教学重点了解作为证明基础的几条公理的内容，掌握证明的基本步骤和书写格式。

教学难点能够用综合法证明等腰三角形的关性质定理和判定定理。

教学后记

教学内容及过程学生活动

一、复习：

1、什么是等腰三角形？

2、你会画一个等腰三角形吗？并把你画的等腰三角形栽剪下来。

3、试用折纸的办法回忆等腰三角形有哪些性质？

二、新课讲解：

在《证明（一）》一章中，我们已经证明了有关平行线的一些结论，运用下面的公理和已经证明的定理，我们还可以证明有关三角形的一些结论。

同学们和我一起来回忆上学期学过的公理

本套教材选用如下命题作为公理:

1.两直线被第三条直线所截,如果同位角相等,那么这两条直线平行;

2.两条平行线被第三条直线所截,同位角相等;

3.两边夹角对应相等的两个三角形全等;（SAS）

4.两角及其夹边对应相等的两个三角形全等;（ASA）

5.三边对应相等的两个三角形全等;（SSS）

6.全等三角形的对应边相等,对应角相等.

由公理5、3、4、6可容易证明下面的推论：

推论两角及其中一角的对边对应相等的两个三角形全等。（AAS）

证明过程：

已知：∠A=∠D,∠B=∠E,BC=EF

求证：△ABC≌△DEF

证明：∵∠A=∠D,∠B=∠E（已知）

∵∠A+∠B+∠C=180°，∠D+∠E+∠F=180°（三角形内角和等于180°）

∠C=180°-(∠A+∠B)

∠F=180°-(∠D+∠E)

∠C=∠F（等量代换）

BC=EF（已知）

△ABC≌△DEF（ASA）

这个推论虽然简单，但也应让学生进行证明，以熟悉的基本要求和步骤，为下面的推理证明做准备。

三、议一议：

（1）还记得我们探索过的等腰三角形的性质吗？WWw.JAB88.COM

（2）你能利用已有的公理和定理证明这些结论吗？

等腰三角形（包括等边三角形）的性质学生已经探索过，这里先让学生尽可能回忆出来，然后再考虑哪些能够立即证明。

定理：等腰三角形的两个底角相等。

这一定理可以简单叙述为：等边对等角。

已知：如图，在ABC中，AB＝AC。

求证：∠B＝∠C

证明：取BC的中点D，连接AD。

∵AB＝AC，BD＝CD，AD＝AD，

∴△ABC△≌△ACD(SSS)

∴∠B=∠C(全等三角形的对应边角相等)

四、想一想：

在上图中，线段AD还具有怎样的性质？为什么？由此你能得到什么结论？

应让学生回顾前面的证明过程，思考线段AD具有的性质和特征，从而得到结论，这一结合通常简述为“三线合一”。

推论等腰三角形的顶角的平分线、底边上的中线、底边上的高互相重合。

五、随堂练习：

做教科书第4页第1，2题。

六、课堂小结：

通过本课的学习我们了解了作为基础的几条公理的内容，掌握证明的基本步骤和书写格式。经历“探索－发现－猜想－证明”的过程。能够用综合法证明等腰三角形的关性质定理和判定定理。探体会了反证法的含义。

七、课外作业：

教科书第5页第1，2题。

板书设计：

这个推论虽然简单，但也应让学生进行证明，以熟悉的基本要求和步骤，为下面的推理证明做准备。

学生充分讨论问题1，借助等腰三角形纸片回忆有关性质

让学生尽可能回忆出来，然后再考虑哪些能够立即证明

让同学们通过探索、合作交流找出其他的证明方法

学生回顾前面的证明过程，思考线段AD具有的性质和特征，讨论图中存在的相等的线段和相等的角，发现等腰三角形性质定理的推论，从而得到结论，这一结合通常简述为“三线合一”。
