Mellish's Theorem: The statements (i) a curve is of constant width; (ii) a curve is of constant diameter; (iii) all the normals of a curve (an oval) are double; (iv) the sum of radii of curvature at opposite points of a curve (an oval) is constant;are equivalent, in the sense that whenever one of statements (i–iv) is true, all other statements also hold.
