一．1.×2.×3.√
二．1.D2.C3.B4.D5.B
三．1.1202.B3.75°4.25
四.
1.解：∵∠2＋∠3=180°
∴a∥b（同旁内角互补，两直线平行）
∵∠3=∠4
∴c∥d（同位角相等，两直线平行）
∵a∥b
∴∠3=∠1＝60°（两直线平行，同位角相等）
∵∠3＋∠5=180°
∠3=60°
∴∠5＝120°
3.利用平行线的内错角相等：两个镜子平行，所以90-∠2=90-∠3所以∠2=∠3，则∠1+∠2=∠3+∠4，即进入光线和离开光线的内错角相等，所以平行

5.y=40-5x(y-40)/-5
6.16(Q-40)/-6
7.10l2206s/t
8.由于两个的值不一样，所以有一个数为负数
当x为负数时，x+y=4|x|+|y|=-x+y=7
解得x=-1.5y=5.5x-y=-7
当y为负数时，x+y=4|x|+|y|=x-y=7
x=5.5y=-1.5x-y=7

4.解：∠AMG=∠3．
理由：∵∠1=∠2，
∴AB∥CD（内错角相等，两直线平行）．
∵∠3=∠4，
∴CD∥EF（内错角相等，两直线平行）．
∴AB∥EF（平行于同一条直线的两直线平行）．
∴∠AMG=∠5（两直线平行，同位角相等）．
又∠5=∠3，
∴∠AMG=∠3．
5.(1)设随身听为x元，书包为y元,
x+y=452x=4y-8将2代入1得4y-8+y=452，解之得y=92，x=360
（2）若在A买的话要花费452*0.8=361.6（元）
若在B买要花费452-30=422（元）
所以他在A超市买更廉价.
1.3
2.C
3.B
4.小红的意思：同位角相等两直线平行
小华的理由：内错角相等两直线平行
另一组平行线：AB//CE理由：∠ABC=∠ECD→AB//CE（同位角相等两直线平行）
