Final answer:
Regular hexagons are always similar to each other because they have the same shape.
Step-by-step explanation:
A. Yes, always
Two regular hexagons share the property of similarity.
A regular hexagon is a polygon with six equal sides and six equal angles. Similarity means that the shapes have the same shape but possibly different sizes.
Since all regular hexagons have the same shape, they are always similar to each other.
