45、.2 空间中直线与直线之间的位置关系1 空间的两条直线有如下三种关系：相交直线：同一平面内，有且只有一个公共点；平行直线：同一平面内，没有公共点；异面直线：不同在任何一个平面内，没有公共点。2 公理 4：平行于同一条直线的两条直线互相平行。符号表示为：设a、b、c 是三条直线ab cb 强调：公理 4 实质上是说平行具有传递性，在平面、空间这个性质都适用。公理 4 作用：判断空间两条直线平行的依据。3 等角定理：空间中如果两个角的两边分别对应平行，那么这两个角相等或互补4 注意点： a 与 b 所成的角的大小只由a、b 的相互位置来确定，与O 的选择无关，为了简便，点O 一般取在两直线中的一条

46、上； 两条异面直线所成的角 (0 ， ) ； 当两条异面直线所成的角是直角时，我们就说这两条异面直线互相垂直，记作 ab； 两条直线互相垂直，有共面垂直与异面垂直两种情形； 计算中，通常把两条异面直线所成的角转化为两条相交直线所成的角。2.1.3 2.1.4 空间中直线与平面、平面与平面之间的位置关系1、直线与平面有三种位置关系：（1）直线在平面内 有无数个公共点（2）直线与平面相交 有且只有一个公共点（3）直线在平面平行 没有公共点指出：直线与平面相交或平行的情况统称为直线在平面外，可用a 来表示a a=A a2.2. 直线、平面平行的判定及其性质2.2.1 直线与平面平行的判定1、直线与平

48、1、定理：一条直线与一个平面平行，则过这条直线的任一平面与此平面的交线与该直线平行。简记为：线面平行则线线平行。符号表示：aa ab = b 作用：利用该定理可解决直线间的平行问题。2、定理：如果两个平面同时与第三个平面相交，那么它们的交线平行。符号表示：= a ab = b 作用：可以由平面与平面平行得出直线与直线平行2.3 直线、平面垂直的判定及其性质2.3.1 直线与平面垂直的判定1、定义如果直线 L 与平面 内的任意一条直线都垂直， 我们就说直线 L 与平面互相垂直，记作 L，直线 L 叫做平面 的垂线，平面 叫做直线 L 的垂面。如图，直线与平面垂直时 , 它们唯一公共点P叫做垂足。

49、 L p 2、判定定理：一条直线与一个平面内的两条相交直线都垂直，则该直线与此平面垂直。注意点： a) 定理中的“两条相交直线”这一条件不可忽视；b) 定理体现了“直线与平面垂直”与“直线与直线垂直”互相转化的数学思想。2.3.2 平面与平面垂直的判定精选学习资料 - - - - - - - - - 名师归纳总结 - - - - - - -第 3 页，共 7 页According to Office Party of mass line education practice activities led group of unified arrangements, units main led
