Yes, it is called a tetrahedron or a triangular pyramid.
5 edges
if its a four sided pyramid then four. if its a three sided pyramid then four.
A 3-sided pyramid.
A quadrilateral based pyramid, of which a square based pyramid would be a special case.
A cube has 12 edges. A 4-sided pyramid has 8 edges. A 3-sided pyramid has 6 edges. There are also other pyramids with more sides.
a four sided pyramid distributes the weight more, so that would be it
A 3-sided pyramid.

Its called a 9 sided pyramid.
An eight sided pyramid would be a heptagon-based pyramid.
A triangular pyramid A triangular pyramid has four sides - each of which is a triangle. There cannot be a three sided pyramid. If you mean a 3 sided Pyramid with its base being the forth side it would be a Quadrangle. A four-sided triangular solid is also called a tetrahedron, and two interlaced are called a Star Tetrahedron.
No because a quadrilateral is a 4 sided 2 dimensional polygon whereas a pyramid is a 3 dimensional polyhedron
if its a four sided pyramid then four. if its a three sided pyramid then four.
A tetrahedron (a triangulat pyramid).
