1、2013 年中考数学角度、长度和面积地计算复习题一、单选题(共 10 道，每道10 分)1.如 图,菱 形ABCD 中,A=110,E,F 分 别 是 边AB 和BC 地 中 点,EGCD 于 点G,则FGC=()A.50 B.55C.110 D.702.如 图,AA,BB分 别 是 EAB,DBC 地 平 分 线.若AA=BB=AB,则 BAC 地 度 数 为()A.25 B.30C.12 D.183.如图所示,以 RtABC 地斜边BC 为一边在 ABC 地同侧作正方形BCEF,设正方形地中心为O,连接 AO,如果 AB=4,AO=,那么 AC=()A.12 B.16 C.D.4.如图,R
2、tABC中,ABC=90,D 为斜边 AC 上一点,连接 BD.E为 BD 上一点,过 E 点作正方形EFGH 和正方形EIJK,使得点F、G 在 BC 边上,点 H、I 在 AC 边上,点 J、K 在 AB 边上.若EF=3,EK=2,则 AC=()A.B.C.D.5.如图,ABC 是边长为3 地等边三角形,BDC 是等腰三角形,且 BDC=120,以 D 为顶点作一个60 角,使其两边分别交AB 于点M 交AC 于点N,连接MN,则 AMN 地周长为()A.5 B.6 C.7 D.8 6.如图,在等边 ABC 中,D 是边AC 上一点,连接BD.将BCD 绕点B 逆时针旋转60 得到BAE
3、,连接 ED.若 BC=10,BD=9,则AED地周长是()A.B.18 C.19 D.20 7.如图,E、F、G、H 分别是四边形ABCD地边 AB、BC、CD,AD地中点,AF、CE交于 K,AG、CH文档编码:CN10W4O9C10A6 HA4B1W7H7V3 ZI8S1K2B8U10文档编码:CN10W4O9C10A6 HA4B1W7H7V3 ZI8S1K2B8U10文档编码:CN10W4O9C10A6 HA4B1W7H7V3 ZI8S1K2B8U10文档编码:CN10W4O9C10A6 HA4B1W7H7V3 ZI8S1K2B8U10文档编码:CN10W4O9C10A6 HA4B1W
