已知:如图,AB=AC,AD=AE,角EAB=角DAC.求证:角D=角E.
已知:如图,AB=AC,AD=AE,角EAB=角DAC.角D=角E.
ab=ac ad=ae,角eab=角dac 求证角d=角e
如图,AB⊥AC,AD⊥AE,AB=AC,AD=AE,已知△DAC≌△EAB.求证BE⊥CD
已知:如图,AB⊥AC,AD⊥AE,AB=AC,AD=AE.求证:△DAC≌△EAB.可能不太好看,
如图AB⊥AC,AD⊥AE,AB=AC,AD=AE.求证:△DAC≌三角形EAB
已知如图,AE=AC,∠E=∠C,∠EAB=∠CAD,求证:AB=AD
已知AE=AC,AB=AD,角EAB=角CAD 1 写已知AE=AC,AB=AD,角EAB=角CAD 1 写出各对全等三角形2求证:AF=AG3求证:角BFD=角BGD
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
AD是三角形ABC的高,角EAB=角DAC,EB垂直AB,证明AD乘AE=AC乘AB
已知AE平行于BC,AD,BD分别平分角EAB,角ABC交EC于点D,EC过点D,求:AB=AE+BC
已知AE平行于BC,AD,BD分别平分角EAB,角ABC交EC于点D,EC过点D,求:AB=AE+BC
已知:如图AE∥BC,AD,BD分别平分角EAB,角CBA,EC过D.求证:AB=AE+BC
如图,AB⊥AC,AD⊥AE,AB=AC,AD=AE,求证:(1)△DAC≌△EAB;(2)BE⊥CD. ,の
已知如图,AE=AC,AB=AD,∠EAB=∠CAD,试说明:∠B=∠D图:
已知:AE=AC,AB=AD,∠EAB=∠CAD.试说明∠B=∠D.(SAS)
如图,已知AB=AC,AE=AD,∠EAB=∠DAC,那么BE与CD相等吗?为什么?
