Question

A student says that a rhombus is a regular polygon because all of its sides are congruent. How do you respond?

Answer 1

You get Detetion.

Answer 2

Sorry but all angles have to be congruent as well to be a regular ploygon, and a rhombus doesn't have to have all congruent angles.

Answer 3

The student is not only wrong, but he or she makes no sense:   "sides are congruent" isn't a thing.  Angles can be congruent, shapes can be congruent, but sides can't be congruent.

Definition of a regular polygon is that all interior angles are equal, and all sides have the same length.  

A rhombus is a 4 sided polygon with all sides of equal length.

So there is one case in which a rhombus is a regular polygon:  a square.
