Parallel Line

How to construct a line parallel to a given line at a given distance?

1. Start with the given line and determine the given distance.

2. Mark two arbitrary points on the given line.

3. Construct a circle, which has the given distance as its radius.

4. Copy circle 3 two times, to points 2 (points 2 become the centers of these circles).

5. Construct two lines perpendicular to the given line from each point 2 upwards. These lines must intersect circles 4.

6. Draw the connecting line between the intersections of lines 5 and circles 4.

7. Line 6 is the line to be constructed, it is parallel to the given line at the given distance.
