如图,AB=AD,AC=AE,∠BAD=∠CAE (1)试说明:△ABC≌△ADE （2）若使AD⊥BC,AF⊥DE,垂足为E、F.如图,AB=AD,AC=AE,∠BAD=∠CAE (1)试说明:△ABC≌△ADE （2）若使AD⊥BC,AF⊥DE,垂足为E、F.试说明AE=AF.（3）如果BC与DE交

如图,AB/AD=BC/DE=AC/AE,求证：∠BAD=∠CAE 如图AB=AD ∠BAD=∠CAE AC=AE 求证AB=AD 如图,∠B=∠E,∠BAD=∠EAC,AC=AD,求证:AB=AE 已知：如图AB=AD,AC=AE,∠BAD=∠CAE ,求证：OA平分∠BOE 如图已知ab=ad,ac=ae∠bad=∠eac是说明bc=de 1、如图1111,AB=AD,∠BAD=∠CAE,AC=AE,求证：DE=BC 如图,AB=AD,AC=AE,∠BAD=∠CAE,连接BC、DE,求证：bc=de 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,AB=AC,∠BAD=30°,AD=AE,则∠EDC=________. 已知:如图,AB/AD=BC/DE=AC/AE,求证:∠BAD=∠CAE 如图,已知AB分之AE = BC分之ED = AC分之AD 证明∠BAD=∠CAE 如图,AB平行AC,∠BAD=∠CAE,AD=AE,求证：△ABE≌△ACD. 如图,DE//BC,请问AD:AC=AE:AB?AD:AE=AB:AC? 如图,在△ABC中,AB=AC,AD为BC边上的中线,∠BAD=25°,AE=AD,则∠EAD=? 如图,已知AD‖BE,AD=BE,AB=CDA,∠BAD=∠D,说明AC=AE 已知:如图,AD平行BC,AE平分∠BAD,AE⊥BE；说明：AD+BC=AB
