One method is to define a minimum district to convex polygon ratio . The convex skull of a polygon is the largest convex polygon contained inside it. The dot product method extends naturally to any convex polygon. None of these three statements holds for a convex polygon. The enclosing-ball-slimness of an "r"-separated convex polygon is at most formula 43. The enclosing-ball-slimness of a "k,r"-separated convex polygon is at most formula 44. The continuous limit of a convex polygon is a parametrized convex curve in the plane. In chromaticity space, the gamut is a plane convex polygon with corners at the primaries. However, not every convex polygon can be inscribed in a circle. Like every regular convex polygon, the regular convex pentagon has a circumscribed circle. Like every regular convex polygon, the regular convex pentagon has an inscribed circle. For the convex polygon, a linear time algorithm for the minimum-area enclosing rectangle is known. The iterates of the pentagram map shrink any convex polygon exponentially fast to a point. In geometry, a zonogon is a centrally symmetric convex polygon. Convex polygons are star shaped, and a convex polygon coincides with its own kernel.
