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.
