This paper considers reconfigurations of polygons, where each polygon edge is a
rigid link, no two of which can cross during the motion. We prove that one can
reconfigure any monotone polygon into a convex polygon; a polygon is
monotone if any vertical line intersects the interior at a (possibly
empty) interval. Our algorithm computes in O(n2) time
a sequence of O(n2) moves, each of which rotates just
four joints at once.
