The segment AB is currently being built. Arcs have been drawn above and below the segment to connect points A that are equidistant from each other. The first arc was drawn with the compass at the same distance, placed at point B, and intersecting the first arc. In the segment above, the arcs intersect at point C. In the segment below, the arcs intersect at point D. From point C to point D, a line was traced. Keeping the compass at the same width allowed the arcs to be drawn for points C and D. A straight edge was used to create segment CD. There was a difference in width between the arcs for points C and D and the compass. A straight edge was used to create segment CD
