3D shapes don't have lines of symmetry they have plane's of symmetry.

there are two plane symmetry on triangular prism.
The answer is 13- for more detail:
A octagonal prism has 32 right angles!!!!!

This depends on the type of prism. If the shapes on the ends are pentagons, the prism has 6 planes of symmetry. If they are hexagons, it has 13 planes of symmetry. It has the same number of planes of symmetry as the shapes on the end have lines of symmetry, plus 1.
there are two plane symmetry on triangular prism.

It must have at least one.
An octagonal prism has 16 vertices (or corners).An octagonal prism has 16 vertices (or corners).An octagonal prism has 16 vertices (or corners).An octagonal prism has 16 vertices (or corners).
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.
