What dual requirement must a pentagon satisfy to be classified as a regular pentagon?

Answer

All five sides must be equal (equilateral) and all five interior angles must be equal (equiangular)

A regular pentagon must satisfy two conditions simultaneously: it must be equilateral, meaning all sides are the same length, and it must be equiangular, meaning all interior angles are the same measure.
