AC and DCB Curves 16 | Some novel theorems for the parabola (with Steven Choi) | Wild Egg Maths

We continue looking at some elementary but interesting properties of the parabola, now associated with a triangle of points on the curve, and the associated dual or polar triangle. Perhaps some of these results are new. This is work with Steven Choi, that appeared in the 2018 paper "The Universal Parabola" in KoG: the Croatian Journal for Geometry and Graphics. ***** Research Gate page: https://www.researchgate.net/profile/...
