北京课改版-八年级上-三角形的初步知识知识点+练习

a 三角形的初步知识 一、三角形的基本概念: 1、三角形的概念:由不在同一条直线上的三条线段首尾顺次相接所组成的图形。 三角形ABC 记作:△ABC 。 2、相关概念: 三角形的边、三角形的内角 3、三角形的分类: ? ? ? ?????等边三角形一般等腰三角形 等腰三角形不等腰三角形按边分:三角形)1( ?? ? ? ? ???? ?钝角三角形等腰直角三角形一般直角三角形直角三角形锐角三角形 按角分:三角形)2( 二、三角形三边关系: 1、三角形任何两边的和大于第三边。(运用) 几何语言:若a 、b 、c 为△ABC 的三边,则a+b>c,a+c>b, b+c>a. 2、三边关系也可表述为:三角形任何两边的差都小于第三边。 三、三角形的内角和定理:(定理、图形、数学语言、证明) 三角形三个内角的和等于1800 。(证明方法) 三角形的外角定理以及证明方法 四、三角形的三线: 问题1、如何作三角形的高线、角平分线、中线? 问题2、三角形的高线、角平分线、中线各有多少条,它们的交点在什么位置? 问题3、三角形的中线有什么应用? 问题4、高有什么应用?(等面积法) 五、三角形的稳定性 C B A

北京课改版三年级数学上册-强化练习题-第一单元

北京课改版3数上-爬坡题 第一单元 乘法 【例1】整十数乘一位数积是120的乘法算式,你能写出多少个。 解析: 因为要写的算式是整十数乘一位数且积是12哦, 只要运用表内乘法,找出积是12的两个数,然后 把两个因数中的一个写成整十数就可以了。积是 12的口诀有两句,在其中一个因数的末尾加上0, 每句口诀都有两种写法,共能写出4道算式。 解答: 20×6=120 60×2=120 30×4=120 40×3=120 【例2】竖式计算。 47×2= 503×3= 340×5= 解析: 依次去乘两位数的每一位,哪一位的积满几十,就 向前一位进几。用一位数乘两位数的十位数时,要 看个位上乘得的积有没有进位,有进位的不要忘记 加上进位数,如果加上进位数后又需要进位,那么还需向百位进位;计算一个因数中间有0的乘法的笔算方法:用一位数去乘多位数的每一位上的数,在与中间的0相乘时,如果没有进上来的数,这一位的积就是0,要在本位上写0占位,如果进上来的数必须加上;一个因数末尾有0的乘法笔算:方法一可以按照学过的多位数乘一位数的方法计算,方法二一位数和多位数0前面的第一个数字对齐,与哪一位相乘所得的积就写在那一位下面。因数末尾有几个0,就在积的末尾添几个0. 解答: 【例3】在□里填上合适的数。 603+604+605+606+607=605×□ 解析: 607减去2加到603上,凑成两个605;606减去 1加到604上,凑成两个605;再加上中间的那个 605,总共5个605,列式为605×5,结果是3025解答: 5 3025 【例4】开心玩具店新进了一批玩具,其中玩具机器人有17个,每个玩具机器人的售价是8元,这些玩具机器人能卖多少钱?

二、写出下列身体部位。 【课堂探究】 1.I have a stomachache.意为:_________________。其中stomachache是名词,意为:____________,是由名词_____________(胃;腹部)加后缀__________(疼痛)构成的复合名词。 提示:此类复合名词还有:背痛__________、牙痛__________、头痛__________等。 2.have a cold 意为:____________ , have 也可以换成catch,即______________。 提示:表示有某种“病症;症状”常用“have + a + 名词”结构,have在此类短语中意为:___________。例如: 发烧________________ 胃痛________________ 咳嗽________________ 3.What’s the matter?意为:____________________。常用于询问对方有什么问题或有什么不顺心的事,也可用于询问某物出了什么故障,后可接with sb./sth.,表示“某人/某物怎么了”。同义句型有: the trouble What’s the problem(with sb./sth.) wrong 4.I think you should lie down and rest.我认为你应该躺下休息。 ①.lie down意为“躺下”,其中lie是动词,意为:_______________。需要注意的是,lie的过去式是__________。注意区分下列词: 原形过去式现在分词 lie(动词)躺,位于lay lying lie(动词)说谎lied lying lay(动词)下蛋;放置laid laying

北京课改版八年级数学(下)知识点总结超经典

北京课改版八年级数学(下)知识点总结(经典) 第十五章一次函数 知识结构图 知识要点 1.常量:在一个过程中,的量叫做常量。 2.变量:在一个过程中,的量叫做变量。 3.函数的概念:一般地,在中,有,对于变量x的, 变量y,我们就把称为自变量,称 为因变量,是的函数。 初中对函数概念的理解,主要应抓住一下三点: ⑴; ⑵; ⑶. 4.定义域:一般地,一个函数的叫做这个函数的定义域。 5.定义域的确定方法 首先考虑自变量的取值必须使函数关系式有意义: ⑴当函数关系式是整式时,函数的定义域是; ⑵当函数关系式是分式时,函数的定义域是; ⑶当函数关系式是二次式时,函数的定义域是; ⑷当关系式中有零指数时,函数的定义域是。 当函数表示实际问题时,其定义域不仅要,而且要。

6. 叫做函数的解析式。 用解析式表示函数关系的方法叫 。 7.用 来表示函数关系的方法叫列表法。 8.用 来表示函数关系的方法叫图像法。 9.平面直角坐标系内的点与 一一对应。 10.四个象限内点的横、纵坐标的特点 第一象限内的点 ; 第二象限内的点 ; 第三象限内的点 ; 第四象限内的点 。 11.特殊位置的点的坐标特点 ⑴x 轴上的点 ;y 轴上的点 。 ⑵第一、三象限角平分线上的点 ; 第二、四象限角平分线上的点 。 ⑶与x 轴平行的直线上的点 ; 与y 轴平行的直线上的点 ; 12.关于坐标轴和原点对称的两对称点的坐标特点 ⑴关于x 轴对称的两个点? ; ⑵关于y 轴对称的两个点? ; ⑶关于原点对称的两个点? 。 13.坐标平面上两点间的距离 ⑴同轴上两点间的距离: ①x 轴上两点间的距离:已知(1x A ,)0、(2x B ,)0,则__________=AB ; ②y 轴上两点间的距离:已知(0P ,)1y 、(0Q ,)2y ,则__________=PQ ; ⑵异轴上两点间的距离:已知(x M ,)0、(0N ,)y ,则__________=MN 。 14.点到坐标轴及原点的距离 ⑴点到坐标轴的距离:①点(x P ,)y 到x 轴的距离_____=d ; ②点(x P ,)y 到y 轴的距离_____=d 。 ⑵点(x P ,)y 到原点的距离_____=d 。 15.函数图像上每一个点的横坐标和纵坐标一定是这个函数的 一组对应值;反之,以 的点必然在这个函数的图像上。 16.画函数图像的一般步骤:⑴ ;⑵ ;⑶ . 17.通常判定点是否在函数图像上的方法: ,如果满足函数解析式,这个点就 函数图像上;如果不满足函数关系式,这个点就 函数图像上。 备注:两个函数图像的交点,就是 的解, 即求两个函数图像的交点坐标,就是 。 18.一般地,如果 ,那么y 叫做x 的一次函数。 特别地,当时 , ,这时y 叫做x 的正比例函数。 19.正比例函数与一次函数的图像是 。 O x y
