None. A triangle based pyramid is a 4-sided solid (a tetrahedron), and has no parallel sides.
A triangular based pyramid has no parallel lines but it does have 4 faces, 6 edges and 4 vertices.
Depends if it's a square based Pyramid or a Triangular based Pyramid. Square based has 5 sides, Triangular based has 4 sides. Hope I could help!
A triangular based pyramid has 4 sides. 3 triangle sides and 1 Square base

None.
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.
four!

Four - as a square has four sides, there are then four triangular sides (meeting at the top of the pyramid).
