已知,如图,AB=AC,AD=AE,BD=CE,AC平分DE.求证:(1)∠BAC=∠DAE;(2)∠BAD=∠CAD.已知,如图,AB=AC,AD=AE,BD=CE,AC平分DE.求证:(1)∠BAC=∠DAE;(2)∠BAD=∠CAD
在△ABD与△ACE中,由三边对应相等知△ABD≌△ACE,得∠BAD=∠CAE; ∠ABD=∠ACE;
∠ADB=∠AEC.还有∠BAC=∠DAE(等量加同量其和相等).另外,△BAC和△DAE分别是等腰三角形且两个顶角相等,于是底角∠ABC=∠ACB=∠ADE=∠AED.
若AD是∠BAC的平分线即∠BAD=∠DAC=(1/2)∠BAC,那么∠DAC=(1/2)∠DAE,可知AC是∠DAE的平分线,也是DE的垂直平分线(等腰三角形顶角的平分线垂直平分底边).
本题中两个等腰三角形形状相似,四个底角彼此相等.

如图如图,图在哪里呀?就这几个条件怎么画呀,还快点,真是的

没有图,怎么做?
