It need not have any.
6 planes of symentry
Since a hexagon is a horizontal plane figure it cannot have a horizontal plane of symmetry.

There are 3 planes of symmetry in a rectange.
there is 9 planes of symmetry in a cube
it has 5 planes of symmetry
Infinitely many planes of symmetry
There are infinite planes of symmetry in a cylinder in the same way that a circle has infinite lines of symmetry.
A rectangular solid that is not a cube has 3 planes of symmetry.
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 no lines of symmetry in a 3d figure.The right question is how planes of symmetry are there in a pentagonal pyramid.Then the correct answer is 5 planes of symmetry.
The tetrahedrom have 11 sides and 11 corners Samantha Avery
