✦ Synopsis

For p ¢ q, let pq = conv{p, q}, Ipql be the length ofpq and ff~ be the ray from p through q. For points p, q and r, let / (p, q, r) be the absolute measure of the angle determined by q"~ and ~ in conv(~'pu~). Thus 0 <~ /(p,q,r) <<. lz.

Henceforth, let S, = {D1,..., D,} be a collection of n >i 1 closed unit disks Di with center c i such that Ic~cjl t> 2 for 1 ~< i ~j ~< n.
