AB=CD,AF=CE,BE⊥AC,DF⊥AC,求证BE=DF

AB=CD,AF=CE,BE⊥AC,DF⊥AC,求证BE=DF AB=CD,DF垂直AC,BE垂直AC,DF=BE.求证:AF=CE 已知AB=CD,AF=CE,BE⊥AC于E,DF⊥AC于F.求证：AB//CD AB=CD,DF⊥AC于F,BE⊥AC于E,DF=BE.试说明：AF=CE 在四边形ABCD中,AB=CD,BE=DF,AF⊥AB,CE⊥CD,求证AB∥CD AB=CD,BE=DF,AF=CE求证BE‖DF AB=CD,DF垂直CD于点F,BE垂直AC于点E,DF=BE,求证AF=CE 如图 AB=CD DF垂直于AC于F BE垂直于AC于E DF=BE 求AF=CE 如图,AB=CD,DF垂直AC于F ,BE垂直AC于E,DF=BE,求证AF=CE. 如图,AB=CD,AF=CE,BE⊥AC于E,DF⊥AC于F,试说明△ABE≌△CDF. 如图,AB=CD,AF=CE,BE⊥AC于E,DF⊥AC于F,求证△ABE≌△CDF AB∥CD,AB=CD,AF=CE,那么BE与DF平行吗?为什么 如图,E,F为AC上两点,AB=CD,BE=DF,AF=CE,那么AB∥CD吗?为什么?（要全过程) 如图,AB=CD,BE=DF,AF=CE.说明(1)BE=DF(2)AB//CD,BE//DF. 如图,已知CE⊥AB,DF⊥AB,AC=BD,AF=BE,则CE=DF.请说明理由. 已知AB=CD,BE=DF,AF=CE 求证：△ABE≌△CDF 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
