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=DF,CE=BF,求证AE平行DF
如图,AB=CD,AE=DF,CE=BF,求证:AE平行DF
如图,已知AB=DC AE=DF .CE=BF 求证:AF=DE
如图,已知AB=DC,AE=DF,CE=BF,求证:AF=DE
如图 已知AB=CD,AE=DF,CE=BF.求证:AF=DE
如图,AB=CD,AE⊥BC,DF⊥BC,CE=BF.求证:AE=DF.
已知:如图,E﹑F是线段BC上的两点,AB∥CD,AB=DC,CE=BF.求证:AE=DF.
如图所示,AB=CD,AE=DF,CE=BF,求证 AE‖DF
AB=CD,AE垂直BC,DF垂直BC,CE=BF,求证AE=DF
如图,己知AB//DC,且AB=CD,BF=DE,求证:AE//CF,AF//CE.
AB=DC.AE=DF.CE=BF.求证:AF=DE.
