如图,已知AB=AC,AE=AD,∠1=∠2,你能说明△ABD≌△ACE吗?

如图,已知AD/DB=AE/EC,求证 :AD/AB=AE/AC. 已知:如图,AC/AD=AB/DE=BC/AE.求证AB=AE 已知,如图,AD/AC=DE/AB=AE/BC,求证AB=AE 已知,如图,AD:AC=DE:AB=AE:BC 求证：AB=AE 如图,已知：AB=AE,AC=AD,AC⊥AD,AB⊥AE.求证：ED⊥BC. 已知：如图,在△ABC中,AD平分∠BAC,DE‖AC交AB于点E,求证：AE：AB+AE：AC=1 如图,已知,AD=AE,AB=AC.试说明∠ABE=∠ACD 如图,DE//BC,请问AD:AC=AE:AB?AD:AE=AB:AC? 如图,已知AB=AC,AB⊥AC,AD⊥AE且∠ABD=∠ACE,求证AD=AE 已知:如图,AD/AB=AE/BC求证：AD/AE=DB/EC和AB/DB=AC/EC 已知:如图,AD/AB=AE/BC求证：AD/AE=DB/EC和AB/DB=AC/EC 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! 已知如图,AB=AC,∠1=∠2,AD⊥CD,AE⊥BE,求证:AD=AE 如图,已知AB=AC,AD=AE,∠1=∠2,说明∠3=∠4 如图,已知AB=AC,AD=AE,∠1=∠2.说明∠3=∠4. 如图,已知AB=AC,AD=AE,∠1=∠2.说明∠3=∠4 如图,已知AB=AD,AC=AE,∠1=∠2,求证∠ADE=∠B 如图,已知AB=AD,AC=AE,∠1=∠2,求证∠ADE=∠B
