Using the diagram below, what theorem or postulate would you use to conclude that c is parallel to d
a) In a plane, if a line is perpendicular to one of two parallel lines, then it is also perpendicular to the other.
b) In a plane, if two lines are perpendicular to the same line, then they are parallel to each other.
c) If two lines are parallel to the same line, then they are parallel to each other.
d) If same-side interior angles are congruent, then the lines are parallel.
