参考答案

一、选择题(本大题共12个小题,每小题4分,共48分.在每小题给出的四个选项中,只有一项是符合题目要求的.)

1.C

【解析】

【分析】

由∠AOC=126°,可求得∠BOC的度数,然后由圆周角定理,求得∠CDB的度数.

【详解】

解:∵∠AOC=126°,

∴∠BOC=180°﹣∠AOC=54°,

∵∠CDB=1

2

∠BOC=27°

故选:C.【点睛】

2.B

【解析】

【分析】

先证明△ABD≌△EBD,从而可得AD=DE,然后先求得△AEC的面积,继而可得到△CDE的面积. 【详解】

∵BD平分∠ABC,

∴∠ABD=∠EBD,

∵AE⊥BD,

∴∠ADB=∠EDB=90°,

又∵BD=BD,

∴△ABD≌△EBD,

∴AD=ED,

3

又∵AD=ED,

∴S△CDE=1

2

S△AEC=

1

6

故选B.

【点睛】

本题考查了全等三角形的判定,掌握等高的两个三角形的面积之比等于底边长度之比是解题的关键. 3.A

【解析】

【分析】

根据旋转的性质可得AC=AC,∠BAC=∠BAC',再根据两直线平行,内错角相等求出∠ACC=∠CAB,然后利用等腰三角形两底角相等求出∠CAC,再求出∠BAB=∠CAC,从而得解

【详解】

∵CC′∥AB,∠CAB=75°,

∴∠C′CA=∠CAB=75°,

又∵C、C′为对应点,点A为旋转中心,

∴AC=AC′,即△ACC′为等腰三角形,

∴∠CAC′=180°﹣2∠C′CA=30°.

故选A.

此题考查等腰三角形的性质,旋转的性质和平行线的性质,运用好旋转的性质是解题关键 4.C 【解析】

试题解析:∵sin ∠CAB=62

BC AC ==

∴∠CAB=45°.

∵B C sin C AB AC '''∠=

==

' ∴∠C′AB′=60°. ∴∠CAC′=60°-45°=15°, 鱼竿转过的角度是15°. 故选C .

考点:解直角三角形的应用. 5.B 【解析】 【分析】

根据乘车人数是25人,而乘车人数所占的比例是50%,即可求得总人数,然后根据百分比的含义即可求得步行的人数,以及骑车人数所占的比例. 【详解】

A 、总人数是:25÷50%=50(人),故A 正确;

B 、步行的人数是:50×30%=15(人),故B 错误;

C 、乘车人数是骑车人数倍数是:50%÷20%=2.5,故C 正确;

D 、骑车人数所占的比例是:1-50%-30%=20%,故D 正确. 由于该题选择错误的, 故选B . 【点睛】

本题考查读频数分布直方图的能力和利用统计图获取信息的能力;利用统计图获取信息时,必须认真观察、分析、研究统计图,才能作出正确的判断和解决问题. 6.D 【解析】 【分析】

根据绝对值的性质,可化简绝对值,根据倒数的意义,可得答案.

|?1

2

|=

1

2

1

2

的倒数是2;

∴|?1

2

|的倒数是2,

故选D.

【点睛】

本题考查了实数的性质,分子分母交换位置是求一个数倒数的关键.7.A

【解析】

试题分析:连接OB,OC,

∵AB为圆O的切线,

∴∠ABO=90°,

在Rt△ABO中,OA=23A=30°,

∴3AOB=60°,

∵BC∥OA,

∴∠OBC=∠AOB=60°,

又OB=OC,

∴△BOC为等边三角形,

∴∠BOC=60°,

则劣弧?BC 6033

π?

=.

故选A.

考点: 1.切线的性质;2.含30度角的直角三角形;3.弧长的计算.

8.B

【解析】

解:∵根据轴对称图形的概念,轴对称图形两部分沿对称轴折叠后可重合,白色的小正方形有13个,而能构成一个轴对称图形的有4个情况,∴使图中黑色部分的图形仍然构成一个轴对称图形的概率是:
