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.
Well, isn't that just a happy little question! A pyramid has multiple lines of symmetry, depending on its shape. A square pyramid has four lines of symmetry, while a triangular pyramid has three. Just imagine how beautiful those symmetrical lines look as they come together to create harmony in the pyramid's structure.

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.
A triangular based pyramid has no lines of symmetry. However, if each of the non-base triangular sides are equal it will have 3 planes of symmetry. If the base triangle is also equal, it will have 6 planes of symmetry.

A triangular pyramid has three lines of symmetry. Each of these lines connects a vertex of the base to the midpoint of the opposite edge on the base.
