【题目】如图,AB|‖CD,AE平分∠BAD,CD与AE相交于点F,∠CFE=∠E。AD与BC有什么位置关系?请说明理由.ADBCE 答案 【解析】AD∥BC ,理由如下:∵AB∥CD ∴∠1=∠CFE ∵ AE平分∠BAD∴∠1=∠2 ∴∠CFE=∠2 ∵∠CFE=∠E ∴∠2=∠E ∴AD∥BC【平行线判定的常用方法】方法一:平行线的定义:在同一平...
(2)如图,在△ABC中,∠ACB=90°,CD为AB边上的高BE平分∠ABC,分别交CD,AC于点F,E,求证:∠CFE=∠CEF.CEFADB 答案 (2)证明: ∵∠ACB=90° ,∴∠1+∠3=90° E∵CD⊥AB ,3∴∠2+∠4=90° .又∵BE平分∠ABC∴∠1=∠2 ,D∴∠3=∠4 .∵∠4=∠5 , ∴∠3=∠5 ,即∠CFE=∠CEF.【点拨...

And it is the one history lesson that is never taught in our schools,thus confirmingthe saying of the German philosopher, Hegel, "We learn from history that men never learn anything from history." 这一历史教训却偏偏是我们的学校从...
∴ AB=AC,AD=AE,∠ BAC=∠ DAE=∠ ABC=(60)^(° ), ∴∠ BAD=∠ CAE, ∴∠ BAD=∠ CAE, ∴∠ ABD=∠ ACE, ∵ AF=CF, ∴∠ ABD=∠ CBD=∠ ACE=(30)^(° ), ∴点E在射线CE上运动(∠ ACE=(30)^(° )), 作点A关于直线CE的对称点M,连接FM交CE于E',此时AE'+FE'的值最小, ∵...
∴∠ B+∠ BCD=180°(理由:两直线平行,同旁内角互补)。故答案为:∠ DAE;两直线平行,内错角相等;∠ DAE;∠ BAE;AB;CD;同位角相等,两直线平行;两直线平行,同旁内角互补. 【平行线判定的常用方法】 方法一:平行线的定义:在同一平面内,不相交的两条直线就是平行线 方法二:平行公理的推论:两条直线都和...
