This subpage contains pairs of constructions for many different curves instead of being dedicated to only one curve. It’s not because this array of curves is less important or less interesting than those commanding an entire subpage; it’s because I don’t have enough material on any specific one of them to make it worthwhile for an entire page. Additionally, most of the constructions will not be 100% geometric; I’m able to use the plotting and graphing capability of my Dynamic Geometry tool, so in many cases, the construction is based on an algebraic interpretation of the curve. As with all of the previous subpages, the first of the pair is a construction that introduces the curve. The second of the pair is my artistic rendering based on the first of the pair, but with all of the mathematical information hidden.
