Yes. Just consider the convex hull and use strong induction.

may be just choose a point A inside the convex hull that not exist B, C from n point that A,B,C lie on the same line. Connect point C to D if angle CAD is min and follow clockwise ( because A inside the convex hull that not exist B, C from n point that A,B,C lie on the same line so CAD < 180 follow clockwise ) . So we can draw n-gon whose vertices are the given points and whose sides do not intersect.
