When constructing parallel lines, how can you verify the lines constructed are parallel?
a. check the intersecting lines with the corner of a piece of paper to ensure the lines create 90° angles.
b. check the distance along the lines at several places with a compass to ensure they are the same length.
c. check the distance between the lines at several places with a compass to ensure they are equidistant.
d. check the angles used in the construction with a straightedge to ensure consistency.
