Examples and Constructions,ant width is undoubtedly the Reuleaux triangle of width . which is the intersection of three disks of radius . and whose boundary consists of three congruent circular arcs of radius .. In Section ., we will see that the Reuleaux triangle can be generalized to plane convex figures of constant width .membrane 发表于 2025-3-25 15:44:10
Sections of Bodies of Constant Width, was not a constructive one, that is, no nonconstant width section of a body of constant width was actually exhibited. In fact, it was proven that if all sections of a convex body have constant width, then the body is a ball. Since there are bodies of constant width other than the ball, it was conclFLOAT 发表于 2025-3-25 18:46:59

Unlike the diameters of a ball, those of a body of constant width do not always meet at a single point, but when they do so, it is because the body is indeed a ball.书法 发表于 2025-3-26 09:18:25
