AB=AE,AC=AD,∠1=∠2.求证△ABC≌△AED

如图,∠1=∠2,AE/AB=AD/AC.求证:△ABC~△AED 如图,AD*AB=AC*AE,求证：△ABC∽△AED 如图,AB=AE,AC=AD,BC=CE,求证△ABC≌△AED 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,角1=角2,AB*AD=AC*AE,求证;ABC∽△AED 如图,在正△ABC中,D,E分别在AC,AB上,且AD/AC=1/3,AE=BE.求证:△AED～△CBD. 已知,如图,ab=ad,ac=ae,∠1=∠2.求证:△abc≌△ade 已知D、E是△ABC的边AC、AB上的点,AD·AC=AE·AB求证△AED∽△ACB 已知:如图,CD,BE是三角形ABC的高.求证:(1).AD:AC=AE:AB (2).角AED 如图,五边形ABCDE中,AB=AE,BC+DE=CD,∠ABC+∠AED=180°,连接AC、AD,求证：AD评分∠C 五边形ABCDE中,AB=AE,AC+DE=CD,∠ABC+∠AED=180度.连接AD,求证AD平分∠CDE 如图,在△ABE中,AB=AE,AD=AC,∠BAD=∠EAC、BC、DE交于点O.求证(△ABC≌△AED)
