Parallel Lines Practice

Questions 1 -3 refer to this image.

a transversal intersecting two lines; the transversal forms vertical angles a and d and vertical angles c and b with the first line; the transversal forms vertical angles e and h and vertical angles g and f with the second line
  1. Which angle forms an alternate exterior angle pair with angle b?
    1. d
    2. f
    3. g
    4. e

    Answer: c. The correct answer is g.
    Angles b and g are alternate exterior angles because the angles are outside the parallel lines, and on opposite sides of the transversal. Angles a and h form the other alternate exterior angle pair in this diagram.

  2. Angle h corresponds to angle _____.
    1. g
    2. a
    3. d
    4. f

    Answer: c. The correct answer is d.
    Other corresponding angle pairs in the diagram are: a and e; b and f; c and g.

  3. Which angle forms a same side interior angle pair with angle e?
    1. c
    2. b
    3. h
    4. e

    Answer: a. The correct answer is c.
    Angles c and e form a same side interior angle pair because they are inside the parallel lines and on the same side of the transversal. Angles d and f form the other same side interior angle pair in this diagram.

    4. Questions 4 - 6 refer to this image.
