已知,如图AB=AC,AD=AE,LBAC=LDAE,求证：LB=LC
已知,如图AB=AC,AD=AE,LBAC=LDAE,求证：LB=LC
已知,如图AB=AC,AD=AE,LBAC=LDAE,求证：LB=LC
L是指角吗?是的话就这样：∵∠BAC=∠DAE∴∠BAC+∠CAD=∠DAE+∠CAD即∠BAD=∠CAE又∵AB=AC,AD=AE∴△ABD≌△ACE∴∠B=∠C
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,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
如图,DE//BC,请问AD:AC=AE:AB?AD:AE=AB:AC?
已知如图AB=AC,求证AB²=AD×AE
如图,已知AD//BC,AD=BC,AE⊥AD,AF⊥AB,AE=AD,AB=AF.求证：AC=EF.
已知,如图AB=AC,AD=AE,LBAC=LDAE,求证：LB=LC
已知；如图,ab=ac,bd=ce,ad=ae.求证be=cd.
全等三角形如图,已知AB=AC,AD=AE,求证BD=CE.
如图,已知AB=AC,AD=AE.求证BD=CE
如图13,已知AB=AC,AD=AE,求证BD=CE
如图,已知,AB=AC,AD=AE,求证：BD=CE
如图,已知AB=AC,AD=AE,求证：BD=CE
如图,已知AB=AC,AD=AE,试说明：BD=CE.
