The Perspector of the Inscribed Parabola
- Steve Phelps
Draw lines from the vertices of the triangle to the point of tangency of the parabola on the opposite side. These three lines are concurrent at the perspector P of the inscribed parabola. This point is on the Steiner circumellipse. The line through the focus F and the perspector P intersect the Steiner circumellipse at the Steiner point S.
