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.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.求证:△DAC≌三角形EAB AD是三角形ABC的高,角EAB=角DAC,EB垂直AB,证明AD乘AE=AC乘AB 如图,AB⊥AC,AD⊥AE,AB=AC,AD=AE,求证:(1)△DAC≌△EAB;(2)BE⊥CD. ,の 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， DA⊥AB EA ⊥AC AB=AD AC=AE 求证 DC=BE 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 如图,AC=AB,AE=AD,∠EAB=∠DAC,求证：BD=CE 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已知：如图,AE=AC,AB=AD,∠EAB=∠CAD 求证：①△ABC全等于△ADE；②∠1=∠2 DA垂直AB,EA垂直AC,AB=AD,AC=AE,BE和CD相交于O,求角DOE的度数. 如图三角形ABC中D为AC上一点,cd=2da,角BAC等于45度,角bdc60度,ce垂直bd,e为垂足.连结ae（1）ed=da (2)角eba=角eab（3）be的平方=ad×ac 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
