Constant breadth curves in the plane
Constant breadth curves in the plane
THEOREM. Under the conditions stated, (2) represents a constant breadth convex curve which is orthogonal to the line family (1) and has a continuously turning tangent line at each point. Letting c approach supe [Dp(0) +J'p(0)dO] from above, a limiting constant breadth convex curve (or a point if F is …
