Abstract

The conics include circle, ellipse, parabola, hyperbola and a pair of intersecting lines. The first and the last can be readily drawn on paper, but there are no constructions for the remaining three using compasses and straight edge. If one has to befriend (i.e., learn about, understand and ultimately develop some intuition based on practical knowledge) a shape, it is important to work with that shape. Paper folding (to be described presently) provided one such way to generate the three remaining conics on paper without much difficulty.
