如图（1），在△ABC中，∠ACB=90°，AC=BC=$\sqrt{2}$，点D在AC上，点E在BC上，且CD=CE，连接DE．

（1）线段BE与AD的数量关系是，位置关系是．

（2）如图（2），当△CDE绕点C顺时针旋转一定角度α后，（1）中的结论是否仍然成立？如果成立，请给予证明；如果不成立，请说明理由．

（3）绕点C继续顺时针旋转△CDE，当90°＜α＜180°时，延长DC交AB于点F，请在图（3）中补全图形，并求出当AF=1+$\frac{\sqrt{3}}{3}$时，旋转角α的度数．

    Do you know the story about Vince? It was a true story. Vince was an English boy and he was eight years old. He didn't like soap or water. Three or four times a day his mother said to him, “Vince, your hands are very dirty again.” Go and wash them. ” But Vince never washed them well. He only put his hands in the water for a few seconds and then took them out again.

Vince's uncle and aunt lived in another city. One day they came to stay with Vince's parents, and they brought their small son, Toby, with them. Toby was seven years old and he didn't like soap or water, either.

    The boys sat with their parents for a few minutes and then they went outside. When they were pla­ying, Vince looked at Toby's hands and then went back to Toby's parents and said proudly (骄傲地）， “Toby's hands are dirtier than mine, ”

    “Of course they are，”Toby said angrily. “You are one year older than I am, ”
