Do all pyramids have atleast 5 or more verticies?

Yes, all pyramids have at least five vertices. A pyramid consists of a base, which is a polygon with a minimum of three sides (a triangle), and a single apex point above the base. For a triangular base, the pyramid would have four vertices (three from the base and one at the apex). However, for any base with more than three sides, the number of vertices increases, resulting in at least five vertices for pyramids with a base of four or more sides.
