如图所示,AE=AC,AB=AD,∠EAB=∠CAD.求证:∠B=∠D.
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,∠E=∠C,∠EAB=∠CAD,求证:AB=AD
已知:如图,AE=AC,AB=AD,∠EAB=∠CAD
已知如图,AE=AC,AB=AD,∠EAB=∠CAD,试说明:∠B=∠D
如图已知AD,BD分别平分∠EAB和∠CBA,EC过点D,AB=AE+BC,求证:AE平行BC
如图,AB=AC,AD=AE.求证:∠B=∠C.
如图,D在AB上,E在AC上,AB=AC,∠B=∠C,求证:AD=AE.
AB=AC,AE=AD,∠EAB=∠DAC,那么BE与CD相等吗?为什么?
已知AB=AD,AC=AE求证(1)∠D=∠B (2)OC=OE
如图,AD,BD分别平分∠EAB和∠ABC,AE垂直EC于E,BC垂直EC于C.求证:AB=AE+BC
已知:D、E分别是△ABC的边AB、AC上的点,且∠AED=∠B 求证:AE.AC=AD.AB
如图,D是三角形ABC的边AC上一点,∠CBD的平分线交AC于E,AE=AB,求证:AE×AE=AD×AC
