Two circles and only a straightedge

Metric Geometry 2018-10-30 v2 History and Overview

Abstract

We answer a question of David Hilbert: given two circles it is not possible in general to construct their centers using only a straightedge. On the other hand, we give infinitely many families of pairs of circles for which such construction is possible.
