Find parametric equations for the curve that consists of all possible positions of the point P in

Question:

Find parametric equations for the curve that consists of all possible positions of the point P in the figure, where | OP | = | AB |. Sketch the curve. (This curve is called the cissoids of Diocles after the Greek scholar Diocles, who introduced the cissoids as a graphical method for constructing the edge of a cube whose volume is twice that of a given cube.)
