Ellipse inscribed in a pentagon
Ellipse inscribed in a pentagon

The applet is about the construction of the unique inellipse inscribed in an arbitrary (convex) pentagon.
The construction is based on the duality of homogeneous lines, points and curves and on the Marden’s Theorem (rather tough subject).
