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.
None
None. A triangle based pyramid is a 4-sided solid (a tetrahedron), and has no parallel sides.
A triangular-based pyramid, also called a tetrahedron, has no parallel faces, but has 4 faces, 6 edges and 4 vertices
A triangular-based pyramid, also called a tetrahedron, has no parallel faces, but has 4 faces, 6 edges and 4 vertices
A triangular pyramid has four faces and 2 pairs.
In a triangular based pyramid, the three faces that form the base are perpendicular to the apex of the pyramid, which means they have pairs of perpendicular sides. The other three faces, which are triangular, do not have pairs of perpendicular sides.
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.
Two pairs
Two pairs.
yes, 2 pairs of congruent faces which are the 4 triangles in the triangular based pyramid:)
