18.(本小题满分 12 分)解:(Ⅰ)连接 BD ,设 BD AC G ,连接 EG , FG , EF . 在菱形 ABCD中,不妨设 GB 1, 由 ABC 120 ,可得 AG GC 3 .
由 BE *面ABCD , AB BC ,可知 AE EC .

又 AE EC ,所以 EG 3 ,且 EG AC .

在 RtEBG 中,可得 BE 2 ,故 DF 2 .在 RtFDG 中,可得 FG 6 .

在直角梯形 BDFE 中,由 BD 2, BE 2 , DF 2 ,可得 EF 3 2 .

2

从而 EG2 FG2 EF 2 ,所以 EG FG ,又 AC FG G ,可得 EG *面AFC .

因为 EG *面AEC ,所以 *面AEC *面AFC .
