.
求作:直线
,使得直线
将
分割成两个等腰三角形.
下面是小红设计的尺规作图过程,
作法:①作
的垂直平分线
,交斜边
于点D;②作直线
,则直线
就是所求作的直线.
根据小红设计的尺规作图过程.

10 . 下面是小明同学设计的“作一个角等于已知角的2倍”的尺规作图过程.
已知:![](https://staticzujuan.xkw.com/quesimg/Upload/formula/6d7b2fe01a33c4825f9974ed9663a99c.png)
求作:
,使
.
作法:如图,
①在射线
上任取一点C;
②作线段
的垂直平分线,交
于点D,交
于点E,连接
.
所以
即为所求的角.
根据小明设计的尺规作图过程,
(1)使用直尺和圆规,补全图形(保留作图痕迹);
(2)完成下面证明(说明:括号里填写依据):
证明:
是线段
的垂直平分线,
________(线段垂直平分线上的点与这条线段两个端点的距离相等).
________.(________________).
