Giving a partial solution to a problem of S. Fekete and G.J. Woeginger [3,4] we show that given a finite set X of points in the plane, it is possible to arrange them on a polygonal path (with the vertex set X) so that every angle on the polygonal path is at least π/9. According to a conjecture of Fekete and Woeginger, π/9 can be replaced by π/6. Previously, the result has not been known with any positive constant.
