How am I supposed to know dorksalot!! Wow u should really know these things!!
It need not have any. A right triangular prism has 12 pairs but could have 14.

it has five faces
5 faces
3D shapes don't have lines of symmetry they have plane's of symmetry.
5
12 lines of symmetry Hope this help u g-spots :P
It has 2 lines of sym
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.
Regular polygons have lines of symmetry equal to the number of sides/angles that they possess so a hexagon would have 6 lines of symmetry. (: * * * * * However, the question is not about a polygon but a polyhedron! A prism with regual hexagonal bases has six lines of symmetry at the bases, but it also has a line of symmetry along the centre of its length. Furthermore, there are infinitely many lines of symmetry in the plane that divides it halfway along its length.
there are two plane symmetry on triangular prism.
It has two 5-tuples and 5 pairs of parallel lines. It need not have any line of symmetry.
