∠BAD=∠CEA,AE=AD.求证 AB=AC

∠BAD=∠CEA,AE=AD.求证 AB=AC AD平行BC AE平行CD BD平分∠ABC 求证AB=CEA 已知如图AB＝AC,AE＝AD,求证：∠BAD＝∠CEA 初二的全等三角形 ∠BDA=∠CEA,AE=AD,求证(1)AB=AC（2）BE=CD 如图,EB=EC,AE＝ED,AD＝BC,且∠BED＝∠CEA.求证四边形ABCD为矩形 （有图）角BDA=角CEA,AE=AD,求证：AB=AC 已知:如图,角BDA=角CEA,AE=AD.求证:AB=AC 如图,角BDA等于角CEA,AE=AD,求证AB=AC 如图,角BDA和角CEA相等,AE=AD.求证AB=AC. 已知△ABC,∠BAC为直角,线段BC上有E、D两点,连接AE和AD,∠BAD=∠BDA,∠CAE=∠CEA,求∠EAD? AB=AD,AC=AE,BC=DE.求证∠BAD=∠CAE 如图,AB/AD=BC/DE=AC/AE,求证：∠BAD=∠CAE 如图AB=AD ∠BAD=∠CAE AC=AE 求证AB=AD 如图所示,AD平行BC,AB=AD+BC,E为CD的中点.求证：AE平分∠BAD. 在梯形ABCD中, AD平行BC,AE平分∠BAD交DC的中点E,AB=AD+BC,求证BE⊥AE. 梯形ABCD中,AD‖BC,AD⊥DC,E是CD的中点,AE比BE=DE比BC,求证:AE平分∠BAD 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
