3.三角形的三边关系:三角形任意两边的和大于第三边,任意两边的差小于第三边。
4.高:从三角形的一个顶点向它的对边所在直线作垂线,顶点和垂足间的线段叫做三角形的高。
5.中线:在三角形中,连接一个顶点和它的对边中点的线段叫做三角形的中线。

义务教育:数学七年级下册电子版教材(冀教版)
教科书一般都要经过教育部门审定,经过试用、修订,然后推广使用。为了方便大家学习借鉴,下面小编精心准备了数学七年级下册电子版教材(冀教版)内容,欢迎使用学习!
(1)要找清楚点在点段上可能存在的位置。通常可用设元法,表示出移动变化后的线段长,在根据题意列方程即可。求线段的长度时,当题目中涉及到线段长度的比例或倍分关系时,通常可以设未知数,运用方程思想求解。
(2)线段分点问题中求线段长度时,若题目中没有给出图形,那么一定要画出各种可能的情况,进行分类计算,避免漏解。求线段的长度时,若出现线段的比值问题,常采用设未知数,利用方程求线段长度。
(3)在处理动点问题时,需要先研究清楚动点运动的方式和路线,此时往往可以借助画图法,然后再根据图示进行判断。在动点折返运动中,线段的对称性以及运动次数的奇偶性非常有用,可以通过研究它们之间的规律来解决题目。
(4)在线段上研究行程问题时,需注意分清楚不同运动阶段的时间节点。在线段上研究动点问题时,需注意结合题干分析是否存在不同的情况,是否需要进行分类讨论。一元一次方程的应用,两点间的距离,灵活运用线段的和、差、倍、分转化线段之间的数量关系是十分关键的一点。

七年级下册《数学》冀教版电子课本(全册电子书)
冀教版教材,河北教育出版社出版的课本。为了方便大家学习借鉴,下面小编精心准备了七年级下册《数学》冀教版电子课本内容,欢迎使用学习!
1、内容难度不同
”冀教版“相对内容困难一些,重视让学生经历观察、操作、推理、想像的过程。“人教版”内容相对简单一些,更注重对问题的探索。
中小学教材都是在国家统一颁布的《课程标准》的指导下编写,并受相关部门审核通过的。国家支持不同版本的教材和创新。
同一年级段同一学科的内容,在不同教材的处理上,有很大的相似性。因为它们都受课程标准的指导。但同时都具备各自的特色以及创新之处。
2、使用地域不同
“人教版”是针对全国范围内编写的,所以在很多地方的学校里面都能看到;而“冀教版”是针对河北范围内的学生编写的,在河北省以外的学校没有那么普遍存在。

初中七年级下册(生物学)电子课本人教版
人教版即由人民教育出版社出版,简称为人教版小学到高中都有这个版本的教材也是大多数学校所用的教材。下面小编为大家带来七年级下册(生物学)电子课本人教版,希望对您有所帮助!
在初一生物课下,经常对所学的知识进行归纳总结是必要的。在理解的基础上加深记忆,以便能够熟练运用,让老师所讲的内容真正被自己 “同化” 吸收。例如初一生物学习了细胞分裂,我会把一个细胞分裂周期中,染色体、DNA、染色单体的数目及关系罗列一下,列成表格,这对以后做题是很有帮助的。
例如在细胞分裂中,先有哪些细胞器参与植物的细胞分裂,又有哪些细胞器参与动物的细胞分裂呢?每节课后都把课本仔细地通读一遍,毕竟有些小知识,需要我们课下来补充。在此基础上,我还会找一些题目做做,我觉得这样不仅可以巩固知识,而且可以拓宽思路、积累总结解决问题的技巧。

人教版七年级下册生物学电子课本最新大全
生物由非细胞生物、原核生物及真核生物组成,那么关于冀少版七年级上册生物电子课本该怎么预习呢?下面小编为大家带来人教版七年级下册生物学电子课本,希望对您有所帮助!
一、注意掌握生物基本概念
初中生物的学习内容都是生物科学的基础知识,有着大量的基本概念,不掌握这些基本概念,是难以学好生物知识的。在学习这些概念时要注意:
1.分清概念之间的关系。例如:染色体DNA和基因之间的关系:染色体是由蛋白质和DNA组成,DNA是生物体内的主要的遗传物质,DNA上有遗传效应的片段是基因。
2.通过实际运用,使概念具体化。例如:阳光是一种重要的生态因素,可以通过解释松树和人参在山地的分布等实例,来具体理解阳光对生物的影响。
3.注意新旧知识的联系。要善于从已有的知识过渡到新知识,找到新知识的内在联系与区别。例如:学习出血急救时,联系以前学习血管特点,根据血流速度特点,判断急救包扎位置。
4.充分利用实物标本、模型、挂图及课本中的插图。有些生命现象仅用文字说明还不够,所以生物课堂上经常出现标本、模型、插图等辅助学习材料,必须充分发挥它们的作用来帮助理解概念。
5.掌握记忆和整理概念的方法,提高学习和复习的效率。生物概念要在理解的基础上来记忆,记忆是有技巧的,例如要点记忆法、比较记忆法和列表记忆法等。 整理概念时可用框架结构法,层次网络法与流程图法等。例如:新陈代谢是生物重要的生命活动,围绕新陈代谢的场所、过程、意义,动植物的区别等方面能够延伸搭建一个条理清晰的知识框架,从而掌握一批基本概念。要学会根据具体内容灵活选择适当方法。
二、认真做好实验
1.实验前,一定要预习,认真阅读实验指导,明确实验目的,弄清实验原理,熟悉实验用品和实验步骤;做实验时,要严格按实验要求操作,仔细观察实验现象,如实记录,认真分析,得出自己的结论。
2.观察中要学会思考、分析、扩展联想。不能停留在为观察而观察,加强观察对学习的促进作用。
三、学习生物科学的研究方法
在生物教材中,有许多学习内容是从对前人所做试验的介绍中引出的,在大量的科学知识中包含着科学研究的过程和方法。应该重视对研究过程的学习,从中领会科学研究的一般方法,体验科学家们不满足于接受现成的结论,善于发现问题,研究问题的探索精神。将其收获应用于学习过程,能提高学习效率,尤其有助于创新意识的培养。
四、要理论联系实际
生物科学也是一门实践性很强的科学,和我们的生产生活息息相关。要学会在日常生活中多做有心人,如:家里的盆栽植物有时片发黄或枯焦现象,这与植物矿质营养有关吗?依据防止食品腐败的主要原理先把食品内的细菌和真菌杀死或抑制它们的生长和繁殖,日常生活中食品应如何保存?等等。不断地在新情境中运用所学知识,有助于对生物知识的理解和掌握,也能发展思维能力和解决问题的能力。理论联系实际的另一个方面是要随时关注生物科学的新发展,了解生物科学的前沿问题,从而增进对科学、技术和社会的相互关系的理解,了解所学知识的社会价值,激发学习生物学知识的兴趣和能力。

粤教粤人版七年级地理下册电子课本(完整)
不是广东所有地方都用粤教版的。除珠海、肇庆、云浮、湛江用人教版之外,其他各地市都是粤教版,人教版和粤教版,从内容上说,基本上大同小异。下面小编为大家带来粤教粤人版七年级地理下册电子课本,希望对您有所帮助!
一、经度
1.经度:为了区别每条经线给标注的度数。
2.零度确定:国际上规定,把通过英国格林尼治天文台旧址(子午宫)的那条经线定为0°经线;0°经线也叫本初子午线。
3.度数划分:由0°经线向东、向西各分为180度。共360度,最大值180度。
4.表示方法:0°经线以东(右)为东经度,用字母E表示,0°经线以西(左)为西经度,用字母W表示。
5.度数变化:东经度向东(右)逐渐增大;西经度向西(左)逐渐增大。
经度数向东(右)增大的是东经度,向东(右)减小的是西经度。东大东经,西大西经。
6.东、西半球的划分:国际上习惯用
20°W和160°E经线圈分出的两个半球,分别叫做东半球、西半球。
①从经度范围看: 20°W往东过00经线到160°E在东半球; 20°W往西过180°度经线到160°E在西半球。
②从经度数看:小于160°E的东经度和小于20°W的西经度在东半球;反之在西半球。
③160°E和20°W既不属于东半球也不属于西半球。
7.几条特殊的线:
0°:本初子午线,东西经线的分界线,东边东经度、西边西经度。
180°:东西经线的分界线,东边西经度、西边东经度。
0°和180°既不属于东经度也不属于西经度。运用中不带符号。
20°W:东西半球分界线,东边东半球、西边西半球。
160°E:东西半球分界线,东边西半球、西边东半球。
20°W、160°E不属于东半球也不属于西半球。不判断这两条经线上的点的东西半球。
二、纬度
1.纬度:为区别每条纬线给标注的度数。
2.零度确定:国际上规定,最长的纬线为0°纬线,即赤道。
3.度数划分:由0°纬线向北、向南各分为90度。共180度,最大值90度。
4.表示方法:赤道以北为北纬,符号N,赤道以南为南纬,符号S。
度数变化:北纬度向北(上)增大,南纬度向北(上)减小。
纬度数向北(上)增大的是北纬度,向南(下)增大的是南纬度。北大北纬、南大南纬。
赤道既不属于北纬度也不属于南纬度。运用中不带符号。
5.南、北半球的划分:以赤道纬线圈分出的两个半球,北边的叫北半球,南边的叫南半球。由于南北纬度的分界线和南北半球的分界线一致,所以:
北纬度在北半球,南纬度在南半球。
赤道既不属于北半球也不属于南半球。
6.高中底纬的划分:30°纬线是中低纬的分界线,60°纬线是中高纬的分界线。30°和60°纬线不属于高中低纬度。
7.几条特殊的纬线:
0°:赤道,最长的纬线,4万千米。既是南北纬度分界限,也是南北半球分界线。图上多是直线。
30°N:中低纬度分界线。以北中纬度以南低纬度。
30°S:中低纬度分界线。以北纬低度以南中纬度。
60°N:中高纬度分界线。以北高纬度以南中纬度。
60°S:中高纬度分界线。以北中纬度以南高纬度。
23.5°N:北回归线,热带与北温带的分界线;太阳直射的最北界线,线上及以南才有直射。靠近赤道北边的虚线。
23.5°S:南回归线,热带与南温带的分界线;太阳直射的最南界线,线上及以北才有直射,以南无直射。靠近赤道南边的虚线。
66.5°N:北极圈,北寒带与北温带分界线;极昼极夜的最南界线,线上及以北才有极昼极夜。靠近北极的虚线。
66.5°S:南极圈,南寒带与南温带分界线;极昼极夜的最北界线,线上及以南才有极昼极夜。靠近南极的虚线。
90°N:北极点,最短的纬线,长度为0km。地球上绝对的北方,其余各地都是他的正北方。
90°S:南极点,最短的纬线,长度为0km。地球上绝对的南方,其余各地都是他的正南方。
8.值得注意的是:在地图上只有南北回归线和南北极圈是虚线,其余的经纬线都必须是实线。
0°经纬线和1800经线运用中不能带符号,其余的经纬线都必须带符号。
