No, a regular pentagon cannot have congruent sides but non-congruent angles. By definition, a regular pentagon has all sides of equal length and all interior angles equal. In a regular pentagon, the angles are each 108 degrees, ensuring that both the sides and angles are congruent. If the sides are congruent but the angles are not, it would be classified as an irregular pentagon instead.
