Abstract

We give a tight upper bound for the polygonal diameter (a.k.a. link diameter) of the interior, resp. exterior, of a simple n-gon, n=3, in the plane as a function of n, and describe ann-gon (n=3) for which both upper bounds (for the interior and for the exterior) are attained simultaneously.
