如图,已知AE∥BC,AE平分∠DAC,求证：AE∥BC.已知AE∥BC，AE平分∠DAC，求证：AB=AC

如图,已知AE∥BC,AE平分∠DAC,求证：AE∥BC.已知AE∥BC，AE平分∠DAC，求证：AB=AC 如图,已知AE∥BC,AE平分∠DAC,求证：AB＝AC 如图,已知AE平分∠DAC,AE平行BC,那么AB=AC吗? 如图,已知AB=AC,AE平分∠DAC,那么AE//BC吗? 如图已知AE平行BC,AE平分角DAC,求证AB=AC 如图,已知AE平行于BC,AE平分角DAC,求证：AB=AC. 已知：如图,AE平分角DAC,AE平行BC求证：AB＝AC 如图,已知AE//BC,且AE平分∠DAC,试说明∠B=∠C的理由 如图,已知∠B=∠C,AE平分∠DAC,那么AE平行BC吗?为什么 如图,已知,AE平分∠DAC,∠B=∠C,说明AE//BC的理由. 如图,AB=AC,AE平分∠DAC.求证:AE平行于BC 如图,AB=AC,AE平分∠DAC.求证:AE平行于BC 如图,已知∠B=∠C,∠DAC=∠B+∠C,AE平分∠DAC,说明AE平行BC 如图,回答下面的问题.已知∠B=∠C,∠DAC＝∠B+∠C,AE平分∠DAC,证明AE//BC. 如图,已知AE∥BC,AE平分∠DAC,求证：AE∥BC.提示：∠DAE为∠1∠EAC为∠2上面打错了已知AE∥BC，AE平分∠DAC求证：AB=AC会的请回答 如图,已知∠B=∠C,AE平分∠DAC如图,已知∠B=∠C,AE平分∠DAC,那么AE平行BC吗?为什么 如图,已知AE平行BC,AE平分角DAC,试说明角B等于角C 已知:如图AE平行BC,AE平方∠DAC,求证:AB=AC
