AB＝CD,AE＝DF,CE＝BF.求证：AE∥DF那个图,EF反一下

AB＝CD,AE＝DF,CE＝BF.求证：AE∥DF那个图,EF反一下 如图,AB＝CD,AE垂直BC,DF垂直BC垂足分别为E,F,CE＝BF.求证AE＝DF. 如图,AB＝CD,AE⊥BC,DF⊥BC,CE=BF求证AE=DF（请用因为所以仔细回答） 如图,ＡＢ＝ＣＤ,ＣＥ垂直于AD,BF垂直于ＡＤ,垂足分别为E,F,AE =DF.求证AB平行CD 如图,已知AB＝DC,AE＝DF,CE＝BF,求证AF＝DE 如图所示,AB=CD,AE=DF,CE=BF,求证 AE‖DF 如图,AB=CD,AE=DF,CE=BF,求证AE平行DF 如图,AB=CD,AE=DF,CE=BF,求证：AE平行DF AB=CD,AE垂直BC,DF垂直BC,CE=BF,求证AE=DF 1、如图,AB＝CD,再添加条件（　）,则可根据SSS得△ABC≌△CDA2、如图,AE=BF,CE=DF,AB=CD,求证CE‖DF第一题的图 已知：如图,AB＝CD,AE＝CF,BE＝DF.求证：AF∥CE 如下图,AB=DC,BF=CE,AE=DF,求证AB//CD 已知:如图,AD=CD CE=BF DF=AE 求证AB‖DC 如图,AB=CD,AE⊥BC,DF⊥BC,CE=BF,求证AE=DF 如图,AB=CD,AE⊥BC,DF⊥BC,CE=BF,求证AE=DF 如图,AB是圆O的直径,CD是弦,AE垂直CD于E,BF垂直CD于F 1.求证EC＝DF 2.若AB＝10,CD＝8,求AE＋BF的值 AB=CD,CE垂直DF,CE=DF,用平移知识证明,AE=BF 如图,在梯形ABCD中,AB//CD,AD=BC,点E,F在AB上,且AE=BF,连接CE,DF.求证：CE=DF .
