    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(同旁內(nèi)角互補(bǔ),兩直線平行)
    ∵∠3=∠4
    ∴c∥d(同位角相等,兩直線平行)
    ∵a∥b
    ∴∠3=∠1=60°(兩直線平行,同位角相等)
    ∵∠3+∠5=180°
    ∠3=60°
    ∴∠5=120°
    3.利用平行線的內(nèi)錯(cuò)角相等:兩個(gè)鏡子平行,所以90-∠2=90-∠3所以∠2=∠3,則∠1+∠2=∠3+∠4,即進(jìn)入光線和離開(kāi)光線的內(nèi)錯(cuò)角相等,所以平行

    7.10l2206s/t
    8.因?yàn)閮蓚€(gè)的值不一樣,所以有一個(gè)數(shù)為負(fù)數(shù)
    當(dāng)x為負(fù)數(shù)時(shí),x+y=4|x|+|y|=-x+y=7
    解得x=-1.5y=5.5x-y=-7
    當(dāng)y為負(fù)數(shù)時(shí),x+y=4|x|+|y|=x-y=7
    x=5.5y=-1.5x-y=7

    P34
    1.A
    2.C
    3.150°
    4.解:∠AMG=∠3.
    理由:∵∠1=∠2,
    ∴AB∥CD(內(nèi)錯(cuò)角相等,兩直線平行).
    ∵∠3=∠4,
    ∴CD∥EF(內(nèi)錯(cuò)角相等,兩直線平行).
    ∴AB∥EF(平行于同一條直線的兩直線平行).
    ∴∠AMG=∠5(兩直線平行,同位角相等).
    又∠5=∠3,
    ∴∠AMG=∠3.
    5.(1)設(shè)隨身聽(tīng)為x元,書(shū)包為y元,
    x+y=452x=4y-8將2代入1得4y-8+y=452,解之得y=92,x=360
    (2)若在A買的話要花費(fèi)452*0.8=361.6(元)
    若在B買要花費(fèi)452-30=422(元)
    所以他在A超市買更便宜.
    1.3
    2.C
    3.B
    4.小紅的意思:同位角相等兩直線平行
    小華的理由:內(nèi)錯(cuò)角相等兩直線平行
    另一組平行線:AB//CE理由:∠ABC=∠ECD→AB//CE(同位角相等兩直線平行)
