如图,已知AB=CD,AD=BC,DE=BF,说明BE=DF

如图,已知AB=CD,AD=BC,DE=BF,说明BE=DF 如图,ad=bc,ab=cd,de=bf,说明df=be 已知:如图,AD=BC,AB=CD,DE=BF求证:BE=DF 已知如图,AB+AD=BC+CD,求证BF+DF=BE+DE 如图,AD=BC,AB=CD,DE=BF,试说明DF=BC. 如图,AD=BC,AB=CD,DE=BF,是说明DF=BE的理由 如图,已知：AB=DC,AD=BC,DE=BF.求证：BE=DF. 如图AD=CB.AB=CD,DE=BF,BE与DF是否相等 r如图,已知AB=CD,AD=CB,DE=BF,求证：BE=DF 如图AB=DC,AD=BC,DE=BF求证BE=DF 如图,AD=BC,AB=DC,DE=BF,求证BE=DF 如图,AB=DC,AD=BC,DE=BF,求证：BE=DF
