pyramid
A really big triangle made by aliens.I never have seen the word "pryrimid" before but "pyramid" is a geometric shape.the shape is formed by a polygon (many sided planar figure) and a point (vertex) not coplanar with the polygon. Join the vertex with the sides of the polygon with triangular faces and yoyu have a pyramid. The pyramid with the fewest sides is a tetrahedron (a triangular pyramid). The regular tetrahedron is the simplest of the solids.The square pyramid has been used since antiquity for buildings.Some very big stone pyramids are in Egypt, Mexico and China.
A pyramid.
A regular pyramid has a regular polygon base and a vertex over the center of the base. By:Cherrylvr :)

vertex
Yes
an angle whose vertex is the center of the polygon and whose sides pass through adjacent vertices.

A pyramid has a polygonal base with all other sides being triangles. As the Egyptians famously demonstrated, a common pyramid has a square base with four triangles meeting at a vertex, but any polygon - regular or irregular - can be used as the base of such a polyhedron.
