study this incomplete image of a geometric construction. this image may result from the construction of:
a. a line parallel to line ab through c
b. a perpendicular to line ab
the next step in this construction is to set the compass width to:
a. line segment dc and draw an arc centered at d intersecting the second arc
b. line segment kc and draw an arc centered at k intersecting the second arc
c. arc ij and draw an arc centered at k intersecting the second arc
d. line segment ci and draw an arc centered at i intersecting the first arc
