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
