Meet the double-straightedge, also known as a parallel ruler. Unlike the traditional single straightedge, this tool allows us to draw precise parallel lines with ease. It opens up a fascinating world of geometric exploration—without the need for a compass. Here I show how to cut of a given length from another line segment. All without the use of circles!
