Best Answer

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.

Ah, a pentagonal prism is a beautiful shape, friend! It has five planes of symmetry, just like the number of sides it has. Each plane can be thought of as a mirror that can reflect the prism perfectly. Isn't that just lovely?
