如图,d.e是△abc的边bc上两点,且ab=ac,ae=ad,试说明∠BAD=∠CAE

解答
ab=ac,则∠ABC=∠ACB;
ae=ad,则∠ADE=∠AED,且∠ADB=180-∠ADE,∠AEC=180-∠AED;
则∠ADB=∠AEC;
△ABD与△ACE相似,∠BAD=∠CAE
推荐
- 已知：如图,点D、E在△ABC的边BC上,AD=AE,∠BAD=∠CAE.求证：AB=AC
- 如图，∠BAD=∠CAE，AB=AD，AC=AE，说明△ABC≌△ADE的理由．
- 如图，在△ABD和△ACE中，AB=AD，AC=AE，∠BAD=∠CAE，连接BC、DE相交于点F，BC与AD相交于点G．求证：BC=DE．
- 如图，已知AB/AD=BC/DE=AC/AE，求证：△ABD∽△ACE．
- 如图,AB=AC,AB的垂直平分线交AC于D点,若AD=BC,∠ABC=72°,点E在BC的延长线上,且CE=CD连AE,求∠CAE
