如图,已知AD⊥AB,AC⊥AE,AD=AB,角C=角E,证明:DC⊥BE.

如图,已知：AB=AE,AC=AD,AC⊥AD,AB⊥AE.求证：ED⊥BC. 如图,已知AD//BC,AD=BC,AE⊥AD,AF⊥AB,AE=AD,AB=AF.求证：AC=EF. 如图,已知AE⊥AD,AF⊥AB,AF=AB,AE=AD=BC,AD‖BC,求证AC⊥EF 如图,AD⊥AE,AB垂直AC,AD=AE,AB=AC,AD⊥AE ,AB=AC,求证：三角形ABD≌三角形ACE 如图,已知AE⊥AD,AF⊥AB,AB//CD,AE=CD,AE=AD,AF=CD,求证AC=EF 已知,如图,AB⊥AC,AB=AC,AD⊥'AE,AD=AE,求证:(1)BE=CD;(2)BC⊥CD急!帮个忙呗! 如图,AB⊥AC,AD⊥AE,AB=AC,AD=AE,已知△DAC≌△EAB.求证BE⊥CD 如图,已知AB=AC,AB⊥AC,AD⊥AE且∠ABD=∠ACE,求证AD=AE 如图,已知：AB⊥AC,AD⊥AE,AB=AC,AD=AE,说明BE=DC的理由 如图,已知AB⊥AC,AD⊥AE,且AB=AC,AD=AE.BE和CD的位置关系如何?并说明理由 如图,已知AB=AD,AC=AE,AB⊥AD,AC⊥AE,说明⊿ABC与⊿ADE全等的理由? 如图,已知AB⊥AC,AD⊥AE,且AB=AC,AD=AE,BE与CD的位置关系如何? 如图,已知AB⊥AC,AD⊥AE,AB=AC,AD=AE,求证△EAC≌△DAB 已知：如图,AB⊥AC,AD⊥AE,AB=AC,AD=AE.求证：△DAC≌△EAB.可能不太好看， 已知,如图,AB⊥AC,AB=AC,AD⊥AE,AD=AE.求证:△ABD≌△ACE 如图 已知AB=AC,AD=AE,BD=CE若AC⊥AC 试探索AE与AD,BD与CE的位置关系 如图,已知AD/DB=AE/EC,求证 :AD/AB=AE/AC. 如图,AB⊥AC,AD⊥AE,AB=AC,AD=AE.求证BE⊥CD
