人教版数学七年级上册第一章有理数正负数知识点总结练习题带答案

数学七年级上（人教版）基础知识点及习题第一章有理数1.1正数和负数正数：正数是大于零的数。

有时为了明确表达意义，在正数前面也加上“+”（正）号，例如+1，+5，+0.01，+13，一般情况下正数前正号省略不写。

负数：负数是小于零的数。

在正数前面加上符号“-”（负）号，书写负数是负号不可以省略。

零既不是正数，也不是负数。

可以理解为“0”是正数与负数的分界点，所以不属于两方的任意一方。

注：①正数和负数表示相反意义的量，例如零上5摄氏度记作“+5”，那么“-5”表示为零下5摄氏度；向正东方向走10米记作“+10”，那么“-10”表示为向正西方向走10米。

②0不只是表示没有，还有其它的意义，例如0摄氏度温度为0的时候，而不是没有温度。

练习1.给下列各数分类，哪些是正数，哪些是负数。

-1，-2.5，0，-3.8，3.6，+150，+5.32.如果支出10元记作-10元，那么+10元的意义是。

浙教版七年级上册数学第6章 6.1集合图形基础知识、课后巩固练习(包含答案)

6.1几何图形学习指要知识要点1、几何图形:点、线、面、体称为几何图形(1)立体图形:所表示的各个部分不在同一个平面内的图形称为立体图形，包括柱体、锥体、球体.柱体包括圆柱和棱柱，锥体包括圆锥和棱锥.有两个面互相平行、其余各面都是四边形并且每相邻两个四边形的公共边都互相平行，由这些面所围成的多面体叫做棱柱;有一个面是多边形，其余各面都是有个公共顶点的三角形，由这些面所围成的多面体叫做棱锥。

(2)平面图形:所表示的各个部分都在同一个平面内的图形称为平面图形，包括直线、射线、角、三角形、平行四边形、梯形和圆等。

2.面分为平面和曲面，线分为直线和曲线。

3.“点动成线，线动成面，面动成体”，反之，“体是由面围成的，面与面相交得线，线与线相交得点”。

4.七巧板:又称“七巧图”、“智慧板”，是中国古老的智力游戏.顾名思义，七巧板是由七块板组成的，完整图案为一个正方形，由这七块板可以变幻出各种不同的图案。

重要提示1.棱柱有直棱柱和斜棱柱之分，但我们只研究直棱柱，其中长方体和立方体属于四棱柱。

2.现实生活中的一些几何体往往是由几个基本几何体组合而成。

3.几何中，面只有大小而无厚薄，线只有长短而无粗细，点只有位置而无大小.平面是平的，可以无限伸展。

4.圆柱与棱柱的区别:圆柱的底面是圆，侧面是曲面;棱柱的底面是多边形，侧面是四边形。

5.圆锥与棱锥的区别:圆锥的底面是圆，侧面是曲面;棱锥的底面是多边形，侧面都是三角形。
