In a previous article in this journal, simple constructions were considered to study the reflective property of a parabola and of a paraboloid. The purpose was to help middle school students understand the importance of the parabola shape and its ability to focus parallel rays. The examples demonstrated a use of the two "Cabri" products to study a 2D object before considering its 3D equivalent. This article considers constructions that allow a study of ellipses, parabolas, hyperbolas and their 3D equivalents, which are more suitable for senior students .
