中考数学易错题复习专题：三角形(1)

三角形易错点1：三角形的概念，三角形中三种重要的线段——角平分线、中线、高.易错题1：如图，点A ，B ，C 分别是线段A 1B ，B 1C ，C 1A 的中点，若△ABC 的面积是1,那么△A 1B 1C 1的面积是______________.CBA1B 1A 1错解：4 正解：7赏析：错解的主要原因在对三角形中线的有关性质理解错误，以为外侧三个三角形与里面的△ABC 面积相等.三角形的一条中线把原三角形分成的两部分是两个等底同高的等积三角形，由此，连接B 1A ，C 1B ，A 1C ，图中的7个小三角形面积均相等，故答案为7.易错点2：三角形三边之间的关系——三角形任意两边之和大于第三边，任意两边之差小于第三边.易错题2：现有3cm ，4cm ，7cm ，9cm 长的四根木棒，任取其中的三根组成一个三角形，那么可组成三角形的个数是……………………………………………………………（）A .1个B .2个C .3个D .4个错解：C 正解：B 赏析：本题对三角形三边的关系理解错误，可能以为三角形任意两边之和大于第三边的对立面是三角形任意两边之和小于第三边，其实，其对立面还包括等于的情况.从四根木棒中任取三根，共有3cm ，4cm ，7cm ；3cm ，4cm ，9cm ；3cm ，7cm ，9cm ；4cm ，7cm ，9cm 四种情况，但3＋4＝7,3＋4＜9，所以这两种情况不能组成三角形，故选B .易错点3：三角形按边、按角的分类，三角形内、外角的性质，特别是外角的两条性质. 易错题3：如图，在△ABC 中，∠ABC ＝50°，∠ACB ＝60°，点E 在BC 的延长线上，∠ABC 的平分线BD 与∠ACE 的平分线CD 相交于点D ，连接AD ，下列结论：①∠BAC ＝70°；②∠DOC ＝90°；∠BDC ＝35°；∠DAC ＝55°.其中，不正确的有………………（）A .①③B .②④C .②D .④F M O NP DA B错解：B 正解：C赏析：本题对①，②，③可利用三角形内角和定理及三角形外角的性质就可判断对错，关键是对④的判断易产生错误本题错解就是这种情况.判断④对错的关键是能否判定AD 是△ABC 的外角∠F AC 的平分线，为此，过点D 分别作DM ⊥AF 于点M ，DN ⊥AC 于点N ，DP ⊥CE 于点P ，由BD ,CD 分别平分∠BAC ，∠ACE ，可得DM ＝DP ，DN ＝DP ，所以DM ＝DN ，由角平分线的判定可得AD 平分∠F AC ，从而可通过计算判断④正确.易错点4：全等三角形的性质，三角形全等的判定，特别是两边一角对应相等的两个三角形不一定全等.易错题4：如图，已知AB ＝DC ，∠ACF ＝∠DBE ，则添加下列条件之一，能判定△ACF ≌△DBE 且是用“SAS ”判断全等的是……………………………………………………（）A .AF ＝DEB .∠A ＝∠DC .AF ∥DED .FC ＝EBF EDC AB错解：A 正解：D赏析：三角形全等的判定方法通常有SAS 、ASA 、SSS 、AAS 四种，本题错解的原因是对SAS 的条件没有理解清楚.两边一角对应相等的情况有两种：一种是SAS ，其条件是两边及其夹角对应相等，另一种是两边及其一组等边的对角对应相等，这样的两个三角形不全等.易错题5：如图，在△ABC 和△ABD 中，AC 与BD 相交于点E ，AD ＝BC ，∠DAB ＝∠CBA ，求证：AE ＝BE .EBCDA错解：∵∠DAB ＝∠CBA ，∴∠DAE ＝∠CBE ，在△ADE 和△BCE 中，∵AD ＝BC ，∠DAE ＝∠CBE ，∠DEA ＝∠CEB ，∴△ADE ≌△BCE （AAS ），∴AE ＝BE .正解：在△ADB 和△BCA 中，∵AD BC DAB CBA AB BA =⎧⎪∠=∠⎨⎪=⎩，∴△ADB ≌△BCA （SAS ），∴∠D ＝∠C . 在△ADE 和△BCE 中，∵AD BC DEA CEB D C =⎧⎪∠=∠⎨⎪∠=∠⎩，∴△ADE ≌△BCE （AAS ），∴AE ＝BE .又解：在△ADB 和△BCA 中，∵AD BC DAB CBA AB BA =⎧⎪∠=∠⎨⎪=⎩，∴△ADB ≌△BCA （SAS ），∴∠ABD ＝∠BAC ，即∠ABE ＝∠BAE ，∴AE ＝BE .赏析：本题错在第一步，由∠DAB ＝∠CBA ，不能得出∠DAE ＝∠CBE ，可能是把未知条件当做已知条件用了.应先根据“SAS ”证△ADB ≌△BCA ，注意，这里的理由是“SAS ”而不是“SSA ”，由“SSA ”不能判断三角形全等，接下来可用“AAS ”或“ASA ”证△ADE≌△BCE 而得出结论，也可根据等腰三角形的判定“等角对等边”得出结论.易错点5：等腰三角形（含等边三角形）的性质与判定.易错题6：已知△ABC 是等边三角形，BD 为中线，延长BC 至点E ，使CE ＝CD ＝a ，连接DE ，则DE ＝__________.EBCDA错解：2a 正解赏析：本题可能以为DE ＝AC 而得出错解，在△DCE 中，用三边的关系也可判断2a 不正确.应先由等边三角形的性质得出BD 垂直平分AC ，∠CBD ＝30°，∠BCD ＝60°，又CE ＝CD ，∴∠E ＝∠CDE ，又∵∠BCD ＝∠E ＋∠CDE ，∴∠E ＝∠CBD ＝30°，∴BD ＝ED .再在Rt △BCD 中，由tan ∠BCD ＝BDCD得出BD ＝CD tan60，也可在Rt △BCD 中先得出BC ＝2CD ，再由勾股定理求得BD，∴DE.易错点6：运用等腰三角形的性质与判定计算或证明有关问题时注意分类讨论思想的运用.易错题7：在△ABC 中，AB ＝AC ，AB 的垂直平分线与AC 所在直线相交所得锐角为40°，则∠B 的度数为_______________.错解：65°正解：65°或25°赏析：本题只考虑了△ABC 中顶角∠BAC 为锐角的情况.由于等腰三角形的顶角可以是锐角，也可以是直角或钝角，∴本题应分三种情况讨论求解：①当∠BAC 为锐角时，如图1：40°图1E BCD A40°图2EBCDA图3EBCDADE 垂直平分AB ，∠ADE ＝40°，则∠A ＝50°，又∵AB ＝AC ，∴∠B ＝∠C ，∴∠B ＝180502︒-︒＝65°；当∠BAC 为钝角时，如图2，DE 垂直平分AB ，∠ADE ＝40°，则∠DAB ＝50°，∴∠BAC ＝180°－50°＝130°，又∵AB ＝AC ，∴∠B ＝∠C ，∴∠B ＝1801302︒-︒＝25°（或：由∠DAB ＝∠B ＋∠C ，而∠B ＝∠C ，∴∠B ＝12∠DAB ＝12×50°＝25°）；当∠BAC 为直角时，如图3，DE ∥AC ，不合题意，此种情况舍去.∴答案为65°或25°.易错点7：全等三角形与等腰三角形的综合应用.易错题8：我们把由不平行于底边的直线截等腰三角形两腰所得的四边形称为“准等腰梯形”.如图1，四边形ABCD 即为“准等腰梯形”，其中∠B ＝∠C .在由不平行BC 的直线AD 截△PBC 所得的四边形ABCD 中，∠BAD 与∠ADC 的平分线交于点E ，若EB ＝EC ，请问当点E 在四边形ABCD 内部时（如图2所示），四边形ABCD 是不是“准等腰梯形”，为什么？若点E 不在四边形ABCD 内部时，情况又将如何？写出你的结论.（不必说明理由）图1BCP D A 图2EBCDA图3BCDA错解：是“准等腰梯形”，理由：∵EB ＝EC ，∴∠EBC ＝∠ECB ，∴∠ABC ＝∠DCB ，∴是“准等腰梯形”.当点E 不在四边形ABCD 内部时，如图3，四边形ABCD 是“准等腰梯形”.正解：如图4，过点E 分别作EF ⊥AB 于点F ，EG ⊥AD 于点G ，EH ⊥CD 于点H .∵AE 、DE 分别平分∠BAD 、∠ADC ，∴EF ＝EG ＝EH .又∵EB ＝EC ，∴Rt △BFE ≌Rt △CHE ，∴∠3＝∠4，又∵EB ＝EC ，∴∠1＝∠2，∴∠1＋∠3＝∠2＋∠4，即∠ABC ＝∠DCB .又∵四边形ABCD 为AD 截某三角形所得，且AD 不平行BC ，∴四边形ABCD 是“准等腰梯形”. 当点E 不在四边形ABCD 内部时，有两种情况：当点E 在四边形ABCD 的边BC 上时，如图5，四边形ABCD 是“准等腰梯形”；当点E 在四边形ABCD 的外部时，如图6，四边形ABCD 是“准等腰梯形”.4321HGF图4EBCD A 图5BCDA 图6BDA赏析：本题中第一问的理由不正确，没有充分利用两条角平分线的条件，第二问没有理解不在四边形内部的含义，不在四边形内部应包括在四边形上和四边形外部两种情况.这两种情况的理由是：当点E 在四边形ABCD 的边BC 上时，如图7，同理可得Rt △BFE ≌Rt △CHE ，∴∠B ＝∠C ，∴四边形ABCD 是“准等腰梯形”；当点E 在四边形ABCD 的外部时，如图8，同理可得Rt △BFE ≌Rt △CHE ，∴∠EBF ＝∠ECH ，∵EB ＝EC ，∴∠EBC ＝∠ECB ，∴∠EBF －∠EBC ＝∠ECH －∠ECB ，即∠ABC ＝∠DCB .∴四边形ABCD 是“准等腰梯形”.HGF 图7BCD A H GF 图8BCD

图3参考答案3.75°或45°或15°解析：分三种情况：如图①，AD为腰上的高，且在△ABC内部，∵AB＝BC，AD＝12BC，∴AD＝12AB，∴12ADAB=,又∵sin∠B＝ADAB,∴sin∠B＝12，∴∠B＝30°，∴底角为180302︒-︒＝75°；如图②，AD为底边上的高，∵AB＝BC，AD⊥BC，∴BD＝CD，又∵AD＝12BC，∴BD＝AD，∴△ABD为等腰直角三角形，∴底角为45°；如图③，AD为腰上的高，且在△ABC外部，∵AB＝BC，AD＝12BC，∴AD＝12AB，∴12ADAB=,又∵sin∠DBA＝ADAB,∴sin∠DBA＝12，∴∠DBA＝30°，又∵∠DBA＝∠B

人教版七年级上册生物易错题中考真题练习（一）1、当你翻动花园、庭院中的花盆或石块时，常常看到一些身体略扁、长椭圆形、灰褐色或黑色小动物在爬行，这就是鼠妇。

我们发现鼠妇经常躲在阴暗潮湿的地方，如石块、花盆的下面。

“湿度对鼠妇的生活有影响吗？”有些同学提出了上面的问题，下面我们就一起来完成探究。

（1）根据所探究的问题，该实验的变量是。

（2）根据你所学的生物知识和经验，你作出的假设是：。

（3）制定计划：将一个硬纸盒一分为二，硬纸盒两侧内的条件应如所示，其他条件都相同。

（4）实施计划：然后在纸盒中央放入10只鼠妇，10分钟内，每隔2分钟统计硬纸盒两侧鼠妇的数量按上述实验计划进行多次实验记录实验现象，并计算出硬纸盒两侧鼠妇的平均数。

实验时为什么要选择10只鼠妇？。

（5）实验现象：硬纸盒潮湿一侧鼠妇的数量（填“大于”“小于”或“等于”）干燥一侧鼠妇的数量。

（6）分析现象，得出结论。

2．为了探究水对种子萌发的影响，某同学在两个花盆中放等量大豆种子进行实验（大豆种子萌发的适宜温度为25℃左右）．请你选出最佳的修改意见（）花盆空气温度水①充足0℃适量浇水②充足25℃不浇水，保持土壤干燥A．两个花盆都应该放在0℃的环境中B．两个花盆都应该适量浇水C．两个花盆都应该放在25℃的环境中D．两个花盆都应该不浇水3．生物与环境的关系非常密切。

【中考英语易错题】易错点01 名词(原卷及答案)

易错点01 名词易错考点【01】词义辨析在中考中，对于名词的考查，更多集中在具体语言环境下名词词义的辨析上。

结合中考，可以看出，多数学生出错，是由于没能准确掌握形（义）近词的细微差别，或不善于结合具体语言环境中加以辨析，而导致失分，建议单词默写时，能做到看英识汉，看汉默英，结合语境，灵活运用。

．．．．．．．．．．．．．．．．．．．牢记：只有把单词放入语境，单词才有灵魂。

易错考点【02】可数名词的数可数名词数的考查，中考永恒的考点，而学生错误，更多的是对于特殊单词的复数变化规则掌握不牢造成的。

如：不规则变化，单复同形，同形复数与规则复数的意义变化，国人复数的变化等。

建议多背多用，借助口诀，巧妙记忆。

可数名词变复数的不规则变化fish鱼sheep羊deer鹿“某国人”的复数形式：中日不变英法变，其余S加后面。

中日不变：a Chinese- --two Chinese a Japanese---four Japanese英法变：an Englishman --- three Englishmen 3个英国人其余S加后面: a German- --five Germans 5个德国人易错考点【03】不可数名词的量出错原因，主要是由于单复数不能正确区分，或对于不可数名词量方法掌握不牢。

突破方法：变复只变计量单位。

可不可数区分口诀：名词分两半，能把原名叫，就是不可数。

如：water, 分成两半，还是water,所以是不可数名词。

易错考点【04】名词所有格记牢名词所有格的不同表达法。

's口诀：分别所有分别's，公共所有最后's，s结尾只加'。

学生失分的主要原因，是对所有格加‘s的规律掌握不牢固，或是不能通过语境来确定是公共所有还是分别所有。

A 12-year-old boy from Hunan invented a new kind of window because of his _________.The window can prevent children from falling out.A.c ommunicationB. celebrationC. honestyD. creativity答案详解：由于句意没有理清，容易出错。

中考易错题1

中考易错题一．选择题1．人类在探索自然规律的过程中，总结出了许多科学研究方法，如：“控制变量法”、“等效替代法”、“类比法”、“理想模型法”等。

下面是初中物理中的几个研究实例：①研究电流时，把电流比作水流；②研究磁场时，引入“磁感线”；③研究动能与速度的关系时，让物体的质量保持不变；④研究光的传播时，引入“光线”。

电源电压220V．由于导线电阻较大，所以在导线上消耗了6W的电功率，那么此时小灯泡的实际功率(灯丝电阻不随温度的变化而变化) ( )A．大于94W B．等于94W c．小下94W D．仍为100W4．若R0是已知阻值的定值电阻，滑动变阻器铭牌磨损，导致阻值未知，则利用下列电路图不能够准确测出未知电阻Rx阻值的是( )5．下列情景可能发生的是A．有人居然用一块冰将一张纸点燃了B．小明在常德的家中用不加盖的铁锅将水烧到了120℃C．传说中项羽能用手提自己的头发将自己提离地面D．宇航员们在太空中行走时可不通过任何工具而自由交谈6．在物理实验课上，小明想观察直流电动机模型的工作情况，将其接入电路，各部分连接完好，结果电动机却不工作，他用手轻轻地碰了一下线圈后，直流电动机模型开始正常转动，其原因可能是A．直流电动机的铜半环与电刷接触不良B．电源电压太低C．线圈刚好处于平衡位置D．线圈中的电流太小7．煤炭是一种重要能源。

初三语文基础知识易错题1

语文基础知识易错题及对策第一讲同学们好！欢迎收看中考易错100题节目！今天是语文学科易错100题第一讲，我将和同学们说说语文基础知识易错题及对策。

语文基础知识积累及运用在近年各地考试中都占有十分重要的地位，这是因为新《课程标准》对语言积累有明确要求。

这一部分内容看似简单，但如果不重视，也很容易出错。

一、语音这类题既考查对汉语拼音规则的掌握情况，又考查对字音的认读，是对语音知识较全面的考查，其考查形式主要有三类：一是客观选择题，如：例1：下列词语中加点的字，注音全都正确的一项是：（）A.沮．丧（jǔ）馈．赠（kuì）强．迫（qiǎnɡ）锲．而不舍（qì）B.哺．育（pǔ）悲怆．（chuànɡ）胚．芽（pēi）参差．不齐（cī）C.弦．乐（xián）炮．制（páo）干涸．（hã）深恶．痛疾（wù）D.衣着．（zhuó）胆怯．（quâ）畸．形（jī）随声附和．（hâ）；（2006年乌鲁木齐市）二是音形互写，这是传统题型，现在很多地区仍用这种方式考查，如：例2：根据汉语拼音写出汉字。

① (jiàn)赏②愉（yuâ）③一丝不 (ɡǒu) ④实事求 (shì)（2006年苏州市）例3：给下列加点的字注音。

荣膺．（）戏谑．（）翘．（）首企盼应．（）运而生（2006年潍坊市）三是把字音放在句子（或是语段）中来灵活考查，有的还放在语文实践活动中考查，如：例4：小雨负责作南京简介：钟山龙蟠，石城虎踞。

屹立在长江之畔的南京，是一座有着近2500年历史的名城。

她具备山川形胜之妖绕，饱含兴衰荣辱之沧桑，是自然和历史恩锡给人类的礼物。

她的一草一木都是风景，一诗一赋都是绝唱，她丰富而厚重的文化哺育了世世代代淳朴、博爱、智慧的南京人民。

(1)文中两个加点的字容易读错，请你注音。

（2分）龙蟠（）哺育（）（2006年南京市）例5：写出拼音替代的字，并给加点字注音。

中考复习《中考经典错题集》ppt课件

错误原因：不理解比热容是物质的一种特性，把“升高到” 理解为“升高”．
解析：物质的比热容是物质的一种特性，只与这种物质的状态有关，与物质的质量无关．故 2 kg 的水倒掉一半，剩下的水的比热容仍然不变，但水结冰状态改变了，比热容也会改变．由 Q＝cm(t－t0)代入数值可算出 t＝70 ℃.
解析：底片上的像由图乙变为图甲，说明“放大”了，由 “放大”则相机靠近镜头前伸知 D 对．
【答案】D
物体离凸透镜越近时，光屏上成的像越大，像距越大．要将被拍景物“放大”，则相机靠近、镜头前伸；若要“缩小”，相机远离、镜头后缩．
【易错题 4】图 4 是投影仪的成像示意图．其中凸透镜的作用是成________(填“等大”、“缩小”或“放大”)、________(填“正立”或“倒立”)的实像，平面镜的作用是________________．如果图中 h＝40 cm，则凸透镜焦距不可能小于________cm.
声音的特征类型．
解析：与其他管乐器发音特性一样，上下推拉活塞是改变了塑料管空气柱的长度，从而改变了音调；音色由发音体的材料决定；响度是由吹“哨子”的力度决定，吹的力越大，气体的振幅越大；声速大小跟介质的种类有关，与发声体无关．
【答案】A
音调一般指声音的高低，和频率有关，和发声体的长短、粗细、松紧有关．
【答案】C
与电压表并联的用电器短路时，才会出现电压表无示数，电流表有示数．跟电压表并联的用电器断路时，才会出现电压表示数几乎等于电源电压，电流表无示数．
【易错题 13】如图 9 所示的电路，电源电压不变，闭合开关 S，灯 L1 和 L2 均发光．一段时间后，一盏灯突然熄灭，而电流表和电压表的示数都不变，出现这一现象的原因可能是( )

中考物理易错题及解析

中考物理易错题及解析1：下列关于力的说法中，正确的是()A.物体受到力的作用，运动状态一定改变B.物体间力的作用是相互的C.物体不受力时，一定处于静止状态D.手推桌子，桌子没动，是因为推力小于摩擦力答案：B解析：A项错误，物体受到平衡力作用时，运动状态不变；B项正确，物体间力的作用是相互的；C项错误，物体不受力时，可能处于静止状态或匀速直线运动状态；D项错误，手推桌子，桌子没动，处于静止状态，推力等于摩擦力。

2：关于惯性，下列说法正确的是()A.运动的物体具有惯性，静止的物体没有惯性B.物体不受外力作用时有惯性，受到外力作用后惯性就被克服了C.同一物体在地球表面比在月球表面惯性大D.惯性是物体的固有属性，一切物体在任何情况下都有惯性答案：D解析：惯性是物体的固有属性，一切物体在任何情况下都有惯性，与物体的运动状态及是否受力无关。

3：关于声现象，下列说法正确的是()A.声音可以在真空中传播B.声音在不同介质中的传播速度相同C.一切发声体都在振动D.只要物体振动，我们就能听到声音答案：C解析：声音不能在真空中传播，A项错误；声音在不同介质中的传播速度不同，B项错误；一切发声体都在振动，C项正确；物体振动产生声音，但人耳听到声音还需要满足一定的条件，如频率在人耳听觉范围内、有足够的响度等，D项错误。

4：下列关于温度、热量和内能的说法中正确的是()A.温度高的物体内能一定大，温度低的物体内能一定小B.物体的内能与温度有关，只要温度不变，物体的内能就一定不变C.内能小的物体也可能将热量传递给内能大的物体D.物体的温度越高，所含热量越多答案：C解析：内能的大小与物体的质量、温度、状态有关，A项错误；内能的大小与物体的质量、温度、状态有关，单比较物体的温度不能判断内能的大小，B项错误；发生热传递的条件是存在温度差，内能小的物体温度可能高，所以内能小的物体也可能将热量传递给内能大的物体，C项正确；热量是一个过程量，不能说物体“含有”或“具有”多少热量，D项错误。
