(1)AE 与 FC 会平行吗 ?说明理由;(2)AD 与 BC 的位置关系如何?为什么 ? (3)BC 平分 DBE 吗?为什么?本章总结本章主要

131、讲述的知识点有相交线与平行线。其中相交线当中,两线相交,共产生两对对顶角,还引入了邻补角的概念。相交的一种特殊情况是垂直,两条直线交角成90。经过直线外一点,作直线的垂线,有且只有一条;点到直线上各点的距离中,垂线段最短。两条直线的另外一种关系是平行,平行就是指两条直线永不相交。平行线之间的距离处处相等。过直线外一点, 作已知直线的平行线,有且只有一条。当同一平面内的三条直线相交时,有三种情况: 一种是只有一个交点;一种是有两个交点,即两条直线平行被第三条直线所截;还有一种是三个交点,即三条直线两两相交。两条直线被第三条直线所截,产生两个交点,形成了八个角(不可分的):同位角: 没有公共顶点的

132、两个角,它们在直线AB,CD的同侧,在第三条直线EF的同旁(即位置相同) ,这样的一对角叫做同位角;内错角: 没有公共顶点的两个角,它们在直线AB,CD之间,在第三条直线EF的两旁(即位置交错) ,这样的一对角叫做内错角;同旁内角: 没有公共顶点的两个角,它们在直线AB,CD之间,在第三条直线EF的同旁,这样的一对角叫做同旁内角;两条直线平行,被第三条直线所截,其同位角,内错角,同旁内角有如下关系:两直线平行,被第三条直线所截,同位角相等;两直线平行,被第三条直线所截,内错角相等两直线平行,被第三条直线所截,同旁内角互补。平行线判定定理:两条直线平行,被第三条直线所截,形成的角有如上所说的性质

133、;那么反过来,如果两条直线被第三条直线所截,形成的同位角相等,内错角相等,同旁内角互补,是否能证明这两条直线平行呢?答案是可以的。FE21DCBA精选学习资料 - - - - - - - - - 名师归纳总结 - - - - - - -第 5 页,共 8 页democracy, mai ntaining social stability in rural areas, to further establish and improve the system of self-governance , guide the village (neighborhood) Committee will c
