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 pentagonal prism has 5 planes of symmetry. This is because it can be divided into 5 identical sections by planes passing through the center of the prism and perpendicular to its bases. Each of these planes divides the prism into two equal halves that are mirror images of each other.
