vertices of the Thomson triangle

K626 is the isogonal transform of K616. It is a nodal cubic with perpendicular nodal tangents passing through the vertices of the Thomson triangle. See Q091 for a generalization.

The nodal tangents are parallel to the asymptotes of the Jerabek hyperbola and to the axes of the Steiner ellipse.
