For |RJ| < 1, the construction sets |PC| to the cube root of |RJ|.
A simple script is used to avoid a cyclic reference in the construction.
Thus, it provides an iterative solution to a problem that cannot be solved by a pure construction.

Move point R' to change |RJ|

Based on Pascal's theorem, the script calculates a tangent throug F on a conic defined by A,B,C,D,E.

The green and black lines illustrate the intermediate results.

Please enable Java for an interactive construction (with Cinderella).
Moving a polygon on the push of a button.

Pressing "Animation!" will trigger the following CindyScript:

p=[[C,H,P],[G,N,Q],[F,M,R],[E,L,S],[D,K,O]];

repeat(100, factor, start->0, stop->1,
forall(p,(#_3).xy=(1-factor)*#_1 + factor*#_2);
repaint();
)
