  1. 在兩條平行線上加上一條截線 會出現 8 隻角 練習6 (每題15秒)

  2. 若 a =480 求 c、f c =? (xx角) f= ? (XXX角,XX //XX)

  3. 若 c =450 求 a、f a =? (xx角) f= ? (XXX角,XX //XX)

  4. 若 f =1200 求 a、c c= ? (XXX角,XX //XX) a =? (xx角)

  5. 若 a =450 求 c、f c =? (xx角) f= ? (XXX角,XX //XX)

  6. 若 c =420 求 a、f a =? (xx角) f= ? (XXX角,XX //XX)

  7. 若 f =1220 求 a、c c= ? (XXX角,XX //XX) a =? (xx角)

  8. 若 a =480 求 d、f、g d =? (xx角) f= ? (XXX角,XX //XX) g =? (xx角)

  9. 若 d =1240 求 a、f、g a =? (xx角) f= ? (XXX角,XX //XX) g =? (xx角)

  10. 若 f =1230 求 a、d、g g =? (xx角) d= ? (XXX角,XX //XX) a =? (xx角)

  11. 若 g =550 求 a、d、f f= ? (xx角) d =? (XXX角,XX //XX) a =? (xx角)

  12. 若 c =550 求 d、e、f d =? (xx角) e= ? (XXX角,XX //XX) f =? (XXX角,XX //XX)

  13. 若 d =1230 求 c、e、f c =? (xx角) e= ? (XXX角,XX //XX) f =? (XXX角,XX //XX)

  14. 若 f =1200 求 c、d、e c =? (XXX角,XX //XX) d= ? (xx角) e=? (xx角)
