Its base has 2 pairs of opposite parallel edges and it has 5 faces, 8 edges and 5 vertices.
A triangular-based pyramid, also called a tetrahedron, has no parallel faces, but has 4 faces, 6 edges and 4 vertices
Two pairs
Only the base can have parallel edges since all other faces are triangular. So, at most one face.
There are 257 topologically different convex octahedra. Many of these will have no parallel faces. It can have four pairs of parallel faces.
A triangular based pyramid has zero pairs of parallel faces. In a triangular based pyramid, all three faces of the base are not parallel to the apex, which means there are no pairs of parallel faces in this type of shape.
Its base has 2 pairs of opposite parallel edges and it has 5 faces, 8 edges and 5 vertices.
A triangular pyramid * * * * * A triangular pyramid has no parallel faces. None. The correct answer is a parallelepiped (special cases: cuboid, cube).
I think a triangular pyramid.

None. A triangle based pyramid is a 4-sided solid (a tetrahedron), and has no parallel sides.

Two pairs
yes, 2 pairs of congruent faces which are the 4 triangles in the triangular based pyramid:)
