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.

A pentagonal pyramid has five planes of symmetry. Each plane of symmetry passes through the apex of the pyramid and divides the pyramid into two equal halves. These planes of symmetry can be visualized as slicing the pyramid vertically or diagonally in different orientations to create mirror images.
A pyramid, being three-dimensional, does not have linesof symmetry.Your question should really be "How many planes of symmetry does a pyramid have?"This answer may vary, depending on your definition of symmetry. But normally the answer "Four" is accepted.

There are no lines of symmetry in a 3d figure.The right question is how planes of symmetry are there in a pentagonal pyramid.Then the correct answer is 5 planes of symmetry.

If it is a right pyramid then four, otherwise one or none.
