Geometric Construction 8


Construct two identical cardioids each rotating about its cusp meeting orthogonally on the line segment joining the cusps.


Let AB be a fixed diameter of a circle O. Through a variable point C on O construct two cardioids with AB and BC as tangents and with the cusps at the distance of 2AB apart.
