Lift the compass, and without adjusting it, place the needle on that point above Point A where the second arc intersected the transversal. Where your first arc crosses the transversal below Point A, place your compass needle on the transversal and adjust the compass to reach the point on the existing line where your first arc crossed it. The first arc, from Point N, should cross the existing line and the transversal the second arc, from Point A, will cross only the transversal somewhere above Point A. Scribe two arcs with the compass needle set on Point N and again on Point A. Set your drawing compass to scribe an arc shorter than the distance from the existing line to Point A. Identify the point where your new transversal intersects the existing line call it Point N (for New!)

You need a drawing compass plus the plain paper, pencil, and straightedge.įor the given line, draw a transversal crossing the existing line and passing through the point not on the line we'll call that Point A (for Above!). You can also construct a line parallel to an existing line passing through a single point, not on the line.

You can label them, identifying each line with two named points and placing arrowheads at the end of the two lines. When you move the ruler, you have parallel lines. Lay the ruler on the paper, holding it carefully, so it does not slip. If using a ruler, this is a one-step process.

How to construct parallel linesĬonstruct parallel lines with a straightedge, a pencil, and plain paper. To symbolize parallel lines in geometry, we use two vertical lines (or slightly slanted lines), like this:īoth of those statements tell us that line AT is parallel to line UP. Parallel line segments making parallel shapes Parallel symbol Think of squares, parallelograms, rectangles, and trapezoids they all have parallel sides made from parallel line segments. Parallel lines are by themselves very interesting, but when you take segments of them, you can construct many polygons.

This differentiates them from skew lines, which exist in three dimensions (two separate planes). To be parallel lines, both lines must exist in the same plane they must be coplanar. It reminds you of what it means! Parallel lines definitionĪ single existing line can have an infinite number of parallel lines, too, simply by picking a point, not on any existing line, and constructing a line parallel to all the existing ones. The English word 'parallel' is a gift to geometricians, because it has two parallel lines in it, in the form of the two side-by-side ls.
