如图已知:直线y=-x+3交x轴于点A,交y轴于点B,抛物线y=ax
2+bx+c经过A、B、C(1,0)三点.
(1)求抛物线的解析式;
(2)若点D的坐标为(-1,0),在直线y=-x+3上有一点P,使△ABO与△ADP相似,求出点P的坐标;
(3)在(2)的条件下,在x轴下方的抛物线上,是否存在点E,使△ADE的面积等于四边形APCE的面积?如果存在,请求出点E的坐标;如果不存在,请说明理由.

如图1,△ABC是等腰直角三角形,四边形ADEF是正方形,D、F分别在AB、AC边上,此时BD=CF,BD⊥CF成立.
(1)当正方形ADEF绕点A逆时针旋转θ(0°<θ<90°)时,如图2,BD=CF成立吗?若成立,请证明;若不成立,请说明理由.
(2)当正方形ADEF绕点A逆时针旋转45°时,如图3,延长BD交CF于点G.
①求证:BD⊥CF;
②当AB=4,AD=
