A regular hexagon has 6 lines of symmetry.
Explanation: A regular hexagon is a six-sided polygon where all sides and angles are equal. The lines of symmetry in a shape are the lines where you can fold the shape such that both halves match perfectly. In the case of a regular hexagon, you can draw a line of symmetry for each vertex to the midpoint of the opposite side, as well as a line of symmetry through the midpoints of opposing sides. Thus, there are six distinct lines of symmetry in a regular hexagon, which showcases its symmetrical properties.
