Which of the following is used to draw a line parallel to a given line?

To draw a parallel line using a ruler and a compass, follow these steps:

1. Draw a straight line segment using your ruler.
2. Place your compass at any point on the line segment and draw an arc that intersects the line on both sides.
3. Without changing the width of the compass, place the compass at one of the two points where the arc intersects the line and draw another arc above the line.
4. Place the compass at the other point where the arc intersects the line and draw a second arc that intersects the previous arc.
5. Using your ruler, draw a straight line between the two points where the second arc intersects the first line segment.
