(A)甲队单独完成这项工程,刚好如期完成;
(B)乙队单独完成这项工程要比规定工期多用4天;
(C)若甲、乙两队合做3天后,剩下的工程由乙队单独做,也正好如期完工.
为了节省工程款,同时又能如期完工,你认为应选择哪一种方案?并说明理由.
(1)如图1,若A,O,D三点在同一条直线上,求证:S△AOC=S△BOD;
(2)如图2,若A,O,D三点不在同一条直线上,△OAB和△OCD不重叠.则S△AOC=S△BOD是否仍成立?若成立,请予以证明;若不成立,也请说明理由.
(3)若A,O,D三点不在同一条直线上,△OAB和△OCD有部分重叠,经过画图猜想,请直接写出S△AOC和S△BOD的大小关系.

(1)请按如下步骤用直尺和圆规作图(保留作图痕迹并在图中标注字母):
①作∠ABC的平分线交AC边于点D;
②在BC的延长线上截取CE=CD;
③连接DE.
(2)求证:BD=DE.
