七下1-6单元数学知识点总结

七下1-6单元数学知识点总结七下 1-6单元知识点总结姓名：第一章、平行线第01讲平行线知识精讲一．同位角、内错角、同旁内角同位角：两个角都在两条直线的同侧并且在第三条直线（截线）的同旁这样一对角叫做同位角．例如∠1和∠5∠3和∠7等都是同位角．内错角：两个角都在两条直线之间并且在第三条直线（截线）的两旁这样一对角叫做内错角．例如∠3和∠5∠4和∠6是内错角．同旁内角：两个角都在两条直线之间并且在第三条直线（截线）的同旁这样一对角叫做同旁内角．例如∠3和∠6∠4和∠5是同旁内角．说明：截线是指同时穿过两条或两条以上的直线（或线段）的直线（或线段）例如在下图中直线EF是截线．第02讲平移与平行线平行线的判定知识精讲一．平行线的公理及推论 1．平行线的概念：在同一平面内不相交的两条直线叫做平行线直线a与直线b互相平行记作a∥b． 2．平行公理：过直线外一点有且只有一条直线与已知直线平行． 3．平行公理的推论：如果两条直线都与第三条直线平行那么这两条直线也互相平行．二．平行线的判定两条直线被第三条直线所截： 1．如果同位角相等那么两直线平行； 2．如果内错角相等那么两直线平行； 3．如果同旁内角互补那么两直线平行．三点剖析一．平行公理及其推论平行线的判定．二．平行线的判定．三．1．不相交的两条直线互相平行一定要注意是在同一平面内否则结论就不一定成立；平行公理及其推论却不需要限定在同一平面内． 2．判定是由“数量关系”确定图形的“位置关系”因此能否找到两直线平行的条件关键是能否正确找到或识别出同位角、内错角、同旁内角．平行线的性质一．平行线的性质 1．两直线平行同位角相等； 2．两直线平行内错角相等； 3．两直线平行同旁内角互补．两条平行线之间的距离：在一条直线上任意找一点向另一条直线作垂线垂线段的长度就是两平行线之间的距离．三点剖析一．平行线的性质角度的计算与证明．二．常见的几种两条直线平行的结论1．两条平行线被第三条直线所截一组同位角的角平分线平行； 2．两条平行线被第三条直线所截一组内错角的角平分线平行； 3．两条平行线被第三条直线所截一组同旁内角的角平分线垂直．三．1．性质是由图形的“位置关系”决定“数量关系”； 2．两条平行线之间的距离其实可看成点到直线的距离．平移知识精讲一．平移的概念平移是指在平面内将一个图形上的所有点都按照某个方向做相同距离的直线移动这样的图形运动叫做图形的平移运动简称平移．二．平移的性质 1．经过平移之后的图形与原来的图形的对应线段平行（或在同一直线上）且相等图形的形状与大小都没有发生变化． 2．经过平移后对应点所连的线段平行（或在同一直线上）且相等．三．平移的作图 1．找出原图形的关键点（如顶点或者端点）． 2．按要求分别描出各个关键点平移后的对应点． 3．按原图将各对应点顺次连接．三点剖析一．平移的性质平移作图．二．平移的性质．三．1．平移不改变图形的形状和大小和方向平移可以不是水平的； 2．有可能平行有可能在同一直线上．第二章、二元一次方程组手动选题手动排序二元一次方程组知识精讲一．二元一次方程的概念含有两个未知数并且两个未知数项的次数都是1的方程叫做二元一次方程．判定一个方程是二元一次方程必须同时满足三个条件： 1．方程两边的代数式都是整式——分母中不能含有字母； 2．有两个未知数----“二元”； 3．含有未知数的项的最高次数为1----“一次”．二．二元一次方程的解使二元一次方程两边的值相等的两个未知数的一组取值叫做二元一次方程的解．在写二元一次方程解的时候我们用大括号联立表示．如：方程的一组解为表明只有当和同时成立时才能满足方程．三．二元一次方程组的概念由几个一次方程组成并且一共含有两个未知数的方程组叫做二元一次方程组．四．二元一次方程组的解二元一次方程组中所有方程（一般为两个）的公共解叫做二元一次方程组的解．五．易错点： 1．和也是二元一次方程组． 2．二元一次方程组的解一定要写成联立的形式如方程组的解是． 3．二元一次方程组的解必须同时满足所有方程即将解代入方程组的每一个方程时等号两边的值都相等．二元一次方程组的解法知识精讲一．消元思想二元一次方程组中有两个未知数如果能“消去”一个未知数那么就能把二元一次方程组转化为我们熟悉的一元一次方程．这种将未知数的个数由多化少、逐一解决的思想叫做“消元”．使用“消元法”减少未知数的个数使多元方程组最终转化为一元方程再逐步解出未知数的值．二．代入消元法 1．代入消元法的概念将方程组中一个方程的某个未知数用含有另一个未知数的代数式表示出来代入另一个方程中消去一个未知数得到一个一元一次方程最后求得方程组的解这种解方程组的方法叫做代入消元法． 2．用代入消元法解二元一次方程组的一般步骤：（1）等量代换：从方程组中选一个系数比较简单的方程将这个方程中的一个未知数（例如y）用另一个未知数（如x）的代数式表示出来即将方程写成的形式；（2）代入消元：将代入另一个方程中消去y得到一个关于x的一元一次方程；（3）解这个一元一次方程求出x的值；（4）回代：把求得的x的值代入中求出y的值从而得出方程组的解；（5）把这个方程组的解写成的形式．三．加减消元法 1．加减消元法的概念当方程中两个方程的某一未知数的系数相等或互为相反数时把这两个方程的两边相加或相减来消去这个未知数从而将二元一次方程化为一元一次方程最后求得方程组的解这种解方程组的方法叫做加减消元法． 2．用加减消元法解二元一次方程组的一般步骤：（1）变换系数：利用等式的基本性质把一个方程或者两个方程的两边都乘以适当的数使两个方程里的某一个未知数的系数互为相反数或相等；（2）加减消元：把两个方程的两边分别相加或相减消去一个未知数得到一个一元一次方程；（3）解这个一元一次方程求得一个未知数的值；（4）回代：将求出的未知数的值代入原方程组的任何一个方程中求出另一个未知数的值；（5）把这个方程组的解写成的形式．三元一次方程组的解法知识精讲一．三元一次方程组的概念含有三个相同的未知数每个方程中含未知数的项的次数都是1并且一共由3个方程组成的方程组叫做三元一次方程组．二．三元一次方程组的解法解三元一次方程组的基本思想是消元．解题步骤：1．利用代入法或加减法消去一个未知数得出一个二元一次方程组； 2．解这个二元一次方程组求得两个未知数的值； 3．将这两个未知数的值代入原方程中较简单的一个方程求出第三个未知数的值从而求得三元一次方程组的解．三．易错点：为把三元一次方程组转化为二元一次方程组原方程组中的每个方程至少要用一次．二元一次方程的应用知识精讲一．二元一次方程的应用列方程（组）解应用题是中学数学联系实际的一个重要方面我们在七年级上学期已经学习过列一元一次方程解应用题其一般步骤可以简单归纳为“审、设、列、解、验、答”列方程组解应用题的步骤与列一元一次方程解应用题的步骤类似具体是： 1．审题：透彻理解题意弄清问题中的已知量和未知量找出问题给出和涉及的相等关系； 2．设元（未知数）：根据题意可以直接设未知数也可以间接设未知数；3．列代数式和方程组：用含所设未知数的代数式表示其他未知数根据题中给出的等量关系列出方程组一般情况下未知数个数与方程个数是相同的； 4．解方程组； 5．检验：检验方程的根是否符合题意； 6．作答：检验后作出符合题目要求的答案．综上所述列方程（组）解应用题的实质是先把实际问题转化为数学问题（设元、列方程（组））再将数学问题解决从而解决实际问题．在这个过程中列方程起着承前启后的作用．因此列方程是解应用题的关键．第03讲含参的二元一次方程组手动选题手动排序含参的二元一次方程组知识精讲一．解含参数的二元一次方程组对于关于x、y的二元一次方程组：（、、、为已知数且与、与、与、与都不能同时为0）．把含参的二元一次方程组化为含参一元一次方程再分类讨论结论如下： 1．当时方程组有唯一解为； 2．时原方程组有无数多组解； 3．当时原方程组无解．三点剖析一．考点：解含参的二元一次方程组含参二元一次方程组参数与解的关系含参二元一次方程组的同解问题．二．重难点： 1．方程的个数少于未知数的个数时方程组有无数多解； 2．含参二元一次方程组的整数解；3．方程组中的参数的取值范围．三．易错点：参数为给定明确取值范围时不要忘了分类讨论．第三章、整式的乘法第01讲整式的乘除手动选题手动排序幂的运算知识精讲一．幂的概念幂的概念：求n个相同因数的积的运算叫做乘方乘方的结果叫做幂在中a叫做底数n叫做指数. 二．幂的运算 1．同底数幂相乘：同底数的幂相乘底数不变指数相加．用式子表示为：（m,n都是正整数）．

二．单项式乘多项式单项式分别与多项式中的每一项相乘然后把所得的积相加；公式为：其中m为单项式a+b+c为多项式. 三．多项式乘多项式将一个多项式中的每一个单项式分别与另一个多项式中的每一个单项式相乘然后把积相加；公式为：．四．易错点：1．单项式与单项式相乘的结果仍然是一个单项式；符号问题：“奇负偶正”； 2．单项式乘多项式以及多项式乘多项式最后的结果一定要合并同类项按运算法则计算避免漏项．整式的除法知识精讲一．同底数幂相除 1．同底数幂相除：同底数的幂相除底数不变指数相减．用式子表示为：（m,n都是正整数）． 2．规定；（p是正整数）．二．单项式除以单项式法则：系数、同底数的幂分别相除作为商的因式对于只在被除式中含有的字母则连同它的指数作为商的一个因式. 说明：例如：被除式为除式为系数分别为3和1故商中的系数为3a的幂分别为和故商中的幂为同理b的幂为另外被除式中含而除式中不含关于c的幂故商中c的幂为. 三．多项式除以单项式多项式中的每一项分别除以单项式然后把所得的商相加；公式为：其中m为单项式a+b+c为多项式. 三点剖析一．考点：同底数幂相除单项式相除多项式除以单项式二．重难点：同底数幂相除单项式相除多项式除以单项式三．易错点：

1．分式的定义：一般地用AB表示两个整式就可以表示成的形式．如果B中含有字母式子就叫做分式． 2．分式有意义的条件：分式的分母不为零． 3．分式值为零的条件：分式的分母不为零且分子为零．二．分式值符号的讨论1．分式值为正的条件：分母不为零且分子分母同号． 2．分式值为负的条件：分母不为零且分子分母异号．三点剖析一．考点：分式的概念二．重难点：分式有意义的条件与因式分解综合三．易错点：所有分式的问题一定要首先考虑分母不为0 分式的基本性质知识精讲一．分式的基本性质 1．分式的基本性质：分式的分子与分母同乘或除以一个不等于0的整式分式的值不变用式子表示其中ABC为整式． 2．分式的约分：利用分式的基本性质约去分式的分子与分母的公因式分式的值不变． 3．最简分式：分子与分母没有公因式． 4．分式的通分：利用分式的基本性质使分子和分母同乘适当的整式把几个异分母的分式化成同分母的分式不改变分式的值． 5．最简公分母：“各个分母”和“所有分式”的最高次幂的积．三点剖析一．考点：分式的基本性质二．重难点：通分约分最简公分母三．易错点：1．利用分式的基本性质进行分式变形是恒等变形不改变分式值的大小只改变形式； 2．应用基本性质时要注意以及隐含的例如若有分式则反之若有分式则不一定等于； 3．注意“都”分子分母要同时乘以或除以同一个式子．第02讲分式的运算手动选题手动排序分式的乘除知识精讲一．分式的乘法分式的乘法法则：分式乘分式用分子的积作为积的分子分母的积作为积的分母．上述法则可以用式子表示为．二．分式的除法分式的除法法则：分式除以分式把除式的分子、分母颠倒位置后与被除式相乘．上述法则可以用式子表示为．三．分式的乘方分式的乘方法则：分式乘方要把分子、分母分别乘方．上述法则可以用式子表示为．三点剖析一．考点：分式的乘除二．重难点：分式乘除中复杂的因式分解三．易错点：a、b、c、d不仅仅是一个符号它们可以表示数也可以表示式子（单项式、多项式等）但必须要使分式有意义所以很多时候需要考虑字母的取值范围．分式的加减知识精讲一．分式的加减1．同分母的分式相加减：分母不变分子相加减． 2．异分母分式的相加减：异分母的分式相加减先通分变为同分母分式再加减．二．分式的混合运算分式的综合运算法则：先乘方再乘除最后加减遇到括号先算括号里面的．三点剖析一．考点：分式的加减二．重难点：分式的运算三．易错点：在进行分式的综合运算时要注意合理的通分、约分、分解因式尽量用最简单的方法和步骤完成答题过程．分式的化简求值知识精讲一．分式的化简求值 1．分式的化简求值分为有条件和无条件两类．有条件化简求值指导思想：瞄准目标抓住条件依据条件推导目标根据目标变换条件． 2．分式的化简与求值常用方法和技巧：（1）分步或者是分组通分；（2）拆项相消或拆分变形；（3）整体代入；（4）取倒数或者利用倒数关系；（5）换元；（6）先约分后通分．二．易错点： 1．分式求值时一定要注意首先满足分式有意义； 2．利用倒数关系对分时进行分式化简求值时一定要将结果再“倒”回来．整数的指数幂知识精讲一．整数的指数幂 1．负整数指数幂：一般地当n是正整数时 2．整数指数幂性质：（1）；（2）；（3）；（4）；（5）．注意：整数指数幂性质中的mn均为整数不再限制为正整数；第03讲分式方程手动选题手动排序分式方程知识精讲一．分式方程 1．分式方程的概念分式方程：分母中含有未知数的方程． 2．分式方程的解法（1）能化简的先化简；（2）方程两边同乘以最简公分母化成整式方程；（3）解整式方程；（4）验根．二．分式方程的实际应用步骤：审题—-设未知数—-列方程—-解方程—-检验—-解答检验时要从方程本身和实际问题两个方面进行检验三点剖析一．考点：分式方程二．重难点：分式方程检验方法：将整式方程的解代入最简公分母若最简公分母不为零则整式方程的解就是原方程的解否则这个解不是原方程的解．三．易错点： 1．解分式方程时方程两边同时乘以最简公分母时最简公分母有可能为零这样就产生了增根因此分式方程一定要检验； 2．对于列分式方程解决实际问题时检验时要从方程本身和实际问题两个方面进行检验．含参的分式方程知识精讲一．增根问题 1．增根：使分式方程的分母为零的未知数的值是分式方程去分母后化成的整式方程的根． 2．由增根求参数的值（1）将原方程化成整式方程；（2）确定增根；（3）将增根代入变形后的整式方程求出参数的值． 3．由分式方程根的情况求参数的取值范围（1）将原方程化成整式方程；（2）把参数看成常数求解；（3）根据根的情况确定参数的取值范围（注意要排除增根时参数的值）．二．整数根问题利用参数取表示未知数再针对不同形式的参数表示形式进行分离常量对分式部分进行整除性讨论再得到分式方程的整数解．三点剖析一．考点：含参的分式方程二．重难点：含参的分式方程三．易错点：讨论整除性问题时一定要注意分式有无意义的问题第六章数据与统计图表一、抽样人们在研究某个自然现象或社会现象时往往会遇到不方便、不可能或不必要对所有的对象做调查的情况于是从中抽取一部分对象作调查这就是抽样。
