Show that a planar curve has infinitely many Bertrand mates.
Can anyone give hints or direction on how to prove this? Thanks

A parallel Bertrand curve is obtained by erecting a normal of constant length at each point on a curve C. Any smooth continuous curve C is a set of infinite connected points, so correspondingly there are infinitely many curved parallels.
