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=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 已知如图AB=DC,AE=DF,CE=FB求证AF=DE 如图,已知AB=DC,AE=DF,CE=FB,求证AF=DE 如图,已知AB等于DC,AE等于DF,CE等于FB,求证AF等于DE 已知:如图,AB=DC,AE=DF,CE=FB,求证:AF=DE 如图,AB=DC,AE=DF,CE=BF,试说明AF=DE 已知：如图,AB＝CD,AE＝CF,BE＝DF.求证：AF∥CE AB=DC.AE=DF.CE=BF.求证：AF=DE. 如图,已知：AD,EF相交于点O,BO＝OC,AB＝DC,BF∥CE.求证：AF∥DE
