Popis:

A kite with angles π/3, 5π/12, 5π/6, and 5π/12, inscribed within a Reuleaux triangle. Among all quadrilaterals, this shape is the one maximizing the ratio of perimeter to diameter: see Ball, D.G. (1973), "A generalisation of π", Mathematical Gazette 57 (402): 298–303, and Griffiths, David; Culpin, David (1975), "Pi-optimal polygons", Mathematical Gazette 59 (409): 165–175.
