The Arbelos in n-Aliquot Parts 1

The applet shows a generalization of the classical arbelos
to the case divided into many chambers by semicircles.

Suppose that we divide the arbelos into n parts by (n-1)
circles each touching at the point of tangency of the two
inner circles of the arbelos. If the n inscribed circles
of the divided area are all congruent, we call the figure
the arbelos in n-aliquot parts.
