But you solved for a square pyri

For a regular square pyramid:

• Lines of symmetry (Axes of rotational symmetry): It has 1 axis of rotational symmetry. This axis passes through the apex (the top point) and the center of the square base. You can rotate the pyramid by $90^\circ$, $180^\circ$, or $270^\circ$ around this axis, and it will look identical.
• Planes of symmetry: It has 4 planes of symmetry.
  • Two planes pass through the apex and the midpoints of opposite sides of the square base.
  • Two planes pass through the apex and opposite vertices of the square base.

So, the previous answer was correct:

• Lines of symmetry: 1
• Planes of symmetry: 4
