A heptagonal pyramid has a total of 8 planes of symmetry. There are 7 vertical planes of symmetry that each pass through one vertex of the heptagonal base and the apex of the pyramid. Additionally, there is 1 horizontal plane of symmetry that bisects the pyramid at the midpoint of the apex and the base.
