  篇二:九年级数学赢在假期答案

  ">解答题

  1. (2012辽宁鞍山8分)如图,某社区有一矩形广场ABCD,在边AB上的M点和边BC上的N点分别有一棵景观树,为了进一步美化环境,社区欲在BD上(点B除外)选一点P再种一棵景观树,使得∠MPN=90°,请在图中利用尺规作图画出点P的位置(要求:不写已知、求证、作法和结论,保留作图痕迹).

  【答案】解:如图所示:

  点P即为所求。

  【考点】作图(应用与设计作图),线段垂直平分线的性质,圆周角定理。

  【分析】首先连接MN,作MN的垂直平分线交MN于O,以O为圆心, MN长为半径画圆,交BD于点P,点P即为所求.

  2. (2012辽宁丹东8分)已知:△ABC在坐标平面内,三个顶点的坐标分别为A(0,3),B(3,4),C(2,2).(正方形网格中, 每个小正方形的边长是1个单位长度)

  (1)画出△ABC向下平移4个单位得到的△A1B1C1,并直接写出C1点的坐标;

  (2)以点B为位似中心,在网格中画出△A2BC2,使△A2BC2与△ABC位似,且位似比为2︰1,并直接写出C2点的坐标及△A2BC2的面积.

  【答案】解:(1)如图,△A1B1C1即为所求,C1(2,-2)。

  (2)如图,△A2BC2即为所求,C2(1,0),△A2BC2的面积:10

  【考点】作图(平移和位似变换)。

  【分析】(1)根据网格结构,找出点A、B、C向下平移4个单位的对应点A1、B1、C1的位置,然后顺次连接即可,再根据平面直角坐标系写出点C1的坐标。

  (2)延长BA到A2,使AA2=AB,延长BC到C2,使CC2=BC,然后连接A2C2即可,再根据平面直角坐标系写出C2点的坐标,利用△A2BC2所在的矩形的面积减去四周三个小直角三角形的面积,列式计算即可得解:

  △A2BC2的面积=6×4- ×2×6- ×2×4- ×2×4=10。

  3. (2012辽宁阜新10分)如图,在由边长为1的小正方形组成的网格中,三角形ABC的顶点均落在格点上.

  (1)将△ABC绕点O顺时针旋转90°后,得到△A1B1C1.在网格中画出△A1B1C1;

  (2)求线段OA在旋转过程中扫过的图形面积;(结果保留π)

  (3)求∠BCC1的正切值.

  【答案】解:(1)画图如下:

  (2)由勾股定理得, ,

  线段OA在旋转过程中扫过的图形为以OA为半径, 为圆心角的扇形,∴ 。

  答:线段OA在旋转过程中扫过的图形面积为 .

  (3)在Rt 中, 。

  答:∠BCC1的正切值是 。

  【考点】网格问题,旋转变换作图,勾股定理,扇形面积,锐角三角函数的定义。

  【分析】(1)根据图形旋转的性质画出旋转后的图形即可。

  (2)先根据勾股定理求出OA的长,再根据线段OA在旋转过程中扫过的图形为以OA为半径,∠AOA1为圆心角的扇形,利用扇形的面积公式得出结论即可。

  (3)直接根据锐角三角函数的定义即可得出结论。

  4. (2012辽宁锦州8分)如图所示,图中的小方格都是边长为1的正方形,△ABC与△A'B'C'是以

  点O为位似中心的位似图形,它们的顶点都在小正方形的顶点上.

  (1)画出位似中心点O;

  (2)直接写出△ABC与△A′B'C'的位似比;

  (3)以位似中心O为坐标原点,以格线所在直线为坐标轴建立平面直角坐标系,画出△A'B'C'关于点 O中心对称的△A″B″C″,并直接写出△A″B″C″各顶点的坐标.

  【答案】解:(1)图中点O为所求:

  (2)△ABC与△A'B'C'的位似比等于2:1 。

  (3)△A''B''C''为所求,A''(6,0); B''(3,-2); C''(4,-4)。

  【考点】作图(位似和中心对称变换),平面直角坐标系和点的坐标。

  【分析】(1)对应点连线的`交点即为位似中心点。

  (2)根据网格中的距离即可写出△ABC与△A′B'C'的位似比。

  (3)作出△A'B'C'关于点 O中心对称的△A″B″C″,根据平面直角坐标系中的位置写出△A″B″C″各顶点的坐标。

  5. (2012辽宁营口8分)如图,在平面直角坐标系中,△ABC的三个顶点坐标分别为A( , )、 B( ,1)、C(0, ).

  (1) 点B关于坐标原点O对称的点的坐标为__________;

  (2) 将△ABC绕点C顺时针旋转 ,画出旋转后得到的△A1B1C;

  (3) 求过点B1的反比例函数的解析式.

  【答案】解:(1)(1,﹣1)。

  (2)作图如下:

  (3)由(2)得B1点坐标为(3,﹣1),

  设过点B1的反比例函数解析式为 ,

  把点B1 (3,﹣1) 代入 中,得 =﹣3 。

  ∴反比例函数解析式为 。

  【考点】作图(旋转变换),关于原点对称的点的坐标,待定系数法,曲线上点的坐标与方程的关系。

  【分析】(1)根据两个点关于原点对称时,它们的坐标符号相反,可得出答案。

  (2)分别找到各点的对应点,然后顺次连接即可得出旋转后得到的△A1B1C。

  (3)根据(2)所得的图形,可得出点B1的坐标,然后利用待定系数发可求出过点B1的反比例函数的解析式。
