如图已知AB=AD,AC=AE,角1等于角2 证明角1等于角CDE

如图已知AB=AD,AC=AE,角1等于角2 证明角1等于角CDE 如图,已知ad等于ae,ab=ac,求证ob等于oc?只有十分钟! 已知：如图,AB=AC,AE=AD,求证：三角形ABC全等于三角形ACE. 已知；如图,角1等于角2,角3等于角4,ac等于ab,求证：ae等于ad 已知角1等于角2等于角3,试说明AB*AE=AD*AC 如图,已知AD/DB=AE/EC,求证 :AD/AB=AE/AC. 如图12.2-11,已知AB=AD,AC=AE,角1等于角2,求证：角ADE等于角B 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. 如图,角BDA等于角CEA,AE=AD,求证AB=AC 如图,AB=AC,AD=AE.求证:角B等于角C 已知：如图,AE=AC,AB=AD,∠EAB=∠CAD 已知：如图,AE=AC,AB=AD,∠EAB=∠CAD已知：如图,AE=AC,AB=AD,∠EAB=∠CAD 求证：①△ABC全等于△ADE；②∠1=∠2 已知:如图,角BDA=角CEA,AE=AD.求证:AB=AC 已知如图,AD/AE=AB/AC,求证角B=角ADE 如图,已知AB等于AC,AD等于AE,角BAD等于角CAE.求证BE等于CD 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!
