已知:如图,∠BAD=∠CAE,AB=AD,AC=AE.求证:△ABC全等于△ADE. 已知:如图AB=AD,AC=AE,∠BAD=∠CAE ,求证:OA平分∠BOE 已知:如图,AB/AD=BC/DE=AC/AE,求证:∠BAD=∠CAE 如图,已知AB=AC,AD=AE,∠BAD=∠CAE.求证:BE=CD. 已知:如图,AB=AD,AC=AE,∠BAD=∠CAE,求证:BC=DE 如图,已知AB=AC,AD=AE,∠BAD=∠CAE,求证:BE=CD 如图,已知AB分之AE = BC分之ED = AC分之AD 证明∠BAD=∠CAE 已知△ABC,作等腰△ABD与等腰△ACE,使AB=AD,AC=AE,∠BAD=∠CAE,直线CD.,BE交于点O (1)如图①,若∠BAD=∠CAE=60°,则∠BOD=___(2)如图二,若∠BAD=∠CAE=α,α为锐角,则∠BOD=____(3)如图 如图,AB/AD=BC/DE=AC/AE,求证:∠BAD=∠CAE 如图已知∠BAD=∠CAE,AB=AD,AC=AE.试说明;∠C=∠E急 已知:如图,点D、E在△ABC的边BC上,AD=AE,∠BAD=∠CAE.求证:AB=AC 已知:如图,点D、E在△ABC的边BC上,AD=AE,∠BAD=∠CAE.求证:AB=AC 已知:如图,AB=AD,AC=AE,∠CAE=∠BAD.求证△EAD≌△CAB画得不好,大概这样 已知:如图,点D、E在△ABC的边BC上,AD=AE,∠BAD=∠CAE.求证:AB=AC【用三线合一】 如图,已知AB=AC,AD=AE,DE=BC,且∠BAD=∠CAE.求证:四边形BCED是矩形 如图,已知AB=AC,AD=AE,DE=BC,且∠BAD=∠CAE.求证:四边形BCED是矩形 如图AB=AD ∠BAD=∠CAE AC=AE 求证AB=AD 19、已知△ABC,作等腰△ABD与等腰△ACE,使AB=AD,AC=AE,∠BAD=∠CAE,直线CD、BE交于点O(1)如图1,若∠ABD=∠CAE=60°,则∠BOD=(2)如图2,若∠ABD=∠CAE=a,a为锐角,则∠BOD= (3)如图③,若∠BAD=∠CAE=α,α为钝
