1.   Are lines and m parallel, skew, or intersecting?
   
    A. cannot be determined B. intersecting
    C. parallel D. skew
    Hint

  2.   Which segments do not intersect
   
    A. B.
    C. D.
    Hint

  3.   Which pair of planes is parallel?
   
    A. Planes FAE and ECB B. Planes ECD and ABF
    C. Planes FDE and DEC D. Planes ABF and AEC
    Hint

  4.   Can parallel lines lie on different planes? Give a reason why or why not.
    A. Yes; parallel lines only do not have to intersect.
    B. No; parallel lines lie on the same plane and intersect at one distinct point.
    C. Yes; skew lines and parallel lines both are on different planes and do not intersect.
