A student is constructing a pair of parallel lines using a compass and ruler. Here are his first steps: Step 1: The student draws his first line and labels it l. He marks a point A for the second line to pass through.

Step 2: He uses a ruler to draw a line that passes through the point A and crosses the line l. He labels the point of intersection B.

What should be his next step?

answer choices

a) Make a new point on line l and draw an arc.

b) Put the compass point on B and make an arc that crosses both of the lines.

c) Use his ruler to draw a straight line through point A that is parallel to line l.
