9 . 新定义:有一组邻边相等且对角互补的四边形叫做等补四边形.如图1,在四边形
中,
,
,则四边形
是一个等补四边形.

(1)在数学活动课上,怡怡小组对等补四边形
进一步探究,发现
平分
.怡怡小组提供的解题思路是:如图2,过点
分别作
于
,
交
的延长线于
,通过证明
,得
,再根据“角的内部到角的两边的距离相等的点在角的平分线上”得到
平分
.请你写出怡怡小组的完整证明过程;
(2)如图3,在平面直角坐标系中,点
、
在
轴上,以
为直径的⊙M交
轴于点
、
,点
为弧
上一动点(不与
、
重合).
①求证:四边形
始终是一个等补四边形;
②在图3中,若
,
,连接
,
,
的值是否会随着点
的移动而变化?若不变化,请求出该定值;若变化,请说明理由.
