Martin drew a pair of perpendicular lines and a pair of parallel lines.
Which of these statements best compares the pairs of perpendicular and parallel lines?
Answer
A: Perpendicular and parallel lines always have a common endpoint.
B: Perpendicular and parallel lines have their lines extending in one direction only.
C: Perpendicular lines are lines that intersect at right angles, and parallel lines are lines that never meet.
D: Perpendicular lines have only one point lying on them and parallel lines have no points lying on them.
