3) With the pointed tip of your compass on a point on the given line, draw an arc that extends both above and below the given line.
This step is crucial as it allows you to create specific points that can be used to ensure that the new line you will draw through the point not on the line maintains the same angle as the original line, ensuring they are parallel.
