A triangular pyramid has 5 planes. * * * * * In fact, a triangular pyramid is also known as a tetrahedron and as its name suggests, it has 4 plane faces.
If it is a right pyramid then four, otherwise one or none.
There are 3 planes of symmetry in a rectange.
five, all looking from the top, one every 72o
There is only one net to a triangular pyramid.
A triangular based pyramid has no lines of symmetry. However, if each of the non-base triangular sides are equal it will have 3 planes of symmetry. If the base triangle is also equal, it will have 6 planes of symmetry.
there are two plane symmetry on triangular prism.

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.
