Приводится решение задачи для случая равносторонних многоугольников.</p></abstract><trans-abstract xml:lang="en"><p>A carpenter’s rule problem is considered for the case of a self-intersecting planar polygon with additional restriction: the index (turning number) of the polygon should be preserved during deformation.
