AB=CD,BE=DF,AF=CE,△ABE与△CDF全等吗?为什么?

AB=CD,BE=DF,AF=CE求证BE‖DF AB=CD,DF垂直AC,BE垂直AC,DF=BE.求证:AF=CE AB=CD,AF=CE,BE⊥AC,DF⊥AC,求证BE=DF 已知AB=CD,BE=DF,AF=CE 求证：△ABE≌△CDF AB∥CD,AB=CD,AF=CE,那么BE与DF平行吗?为什么 在四边形ABCD中,AB=CD,BE=DF,AF⊥AB,CE⊥CD,求证AB∥CD 如图,AB=CD,BE=DF,AF=CE.说明(1)BE=DF(2)AB//CD,BE//DF. AB=CD,BE=DF,AF=CE,△ABE与△CDF全等吗?为什么? 如图,已知AB‖CD,AB=CD,AF=CE,试说明BE=DF 已知ab平行cd,ab=CD,BE=DF,求证af平行ce,ae=cf 已知AB=CD,AF=CE,BE⊥AC于E,DF⊥AC于F.求证：AB//CD 已知:点A、F、E、C、在同一条线上,AF=CE,BF平行DF,BE=DF.求证:AB平行CD AB=CD,DF垂直CD于点F,BE垂直AC于点E,DF=BE,求证AF=CE 已知四边形ABCD,延长AB到E使BE=DF,连接CE、AF.求证:AF=CE平行四边形 延长CD到F 如图,在四边形ABCD中,AB=CD,BE=DF,AF⊥AB,CE⊥CD,求证:AB||CD 已知∠1=∠2,CB=CD,CE⊥AB,CF⊥AF,求证 BE=DF 已知CD平行AB,DF平行EB,DF=EB,问AF=ce吗, AB=CD,DF⊥AC于F,BE⊥AC于E,DF=BE.试说明：AF=CE
