Abstract

This expository paper considers real cubic plane curves as combinations $C = a_{1} T_{1} + a_{2} T_{2}$ of two real triangles meeting in nine distinct points. Our study of hexagonal pencils, defined by $C$ with parameters $a_{i} \in R$ , picks up on some themes of a recent paper on cubics by Bonifant and Milnor (2017).
