AB=AE,AC=AD,∠1=∠2.求证△ABC≌△AED

已知∠1=∠2=∠3求证AE·AC=AD·AB求证AE·AC=AD·AB 若∠1=∠2=∠3,AC=AE,求证：AB=AD., 如图所示,AB=AC,AD=AE,DC=EB,求证∠1=∠2? 已知∠1=∠2,AD=AE 求证AB=AC 已知AB=AC,AE=AD,∠1=∠2.求证:∠3=∠4 已知:如图,AB=AD,AC=AE,∠1=∠2.求证:△ABC≌△ADE. 已知,如图,ab=ad,ac=ae,∠1=∠2.求证:△abc≌△ade 已知,如图,AB=AC,AD=AE,∠1=∠2.求证：△ABD≌△ACE. 如图,已知：AB=AC、AD=AE、∠1=∠2.求证：△ABD≌△ACE. AB=AE,AC=AD,∠1=∠2.求证△ABC≌△AED AB=AE,AC=AD,∠1=∠2.求证△ABC≌△AED 如图所示,AB=AC,AD=AE,∠1=∠2.求证：△ABC≌△ACERT 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 已知AB=AC,AD=AE,∠BAC=∠DAE.求证：BD=CE. AB=AC AD=AE ∠BAE=∠CAD 求证；BD=CE. AB=AD,AC=AE,BC=DE.求证∠BAD=∠CAE 已知AB=AC AD=AE BD=CE求证 ∠CAB=∠EAD 如图AB=AD ∠BAD=∠CAE AC=AE 求证AB=AD
