Regular pyramids are ones where the base is a regular polygonregular polygonA regular hexagon is defined as a hexagon that is both equilateral and equiangular. It is bicentric, meaning that it is both cyclic (has a circumscribed circle) and tangential (has an inscribed circle). times the apothem (radius of the inscribed circle). All internal angles are 120 degrees.Hexagon – Wikipedia (all sides and angles the same) of any number of sides. The simplest regular pyramid then is a 4-sided pyramid (base + 3 sides). Its proper name is a tetrahedron”.

Can you have a 3 sided pyramid?
The proper name for a three-sided pyramidthree-sided pyramidThe tetrahedral numbers are: 1, 4, 10, 20, 35, 56, 84, 120, 165, 220, … (sequence A000292 in the OEIS)Tetrahedral number – Wikipedia is a tetrahedron. Tetrahedrons have three showing sides formed by three triangles of equal dimensions. The base or bottom of a tetrahedron is also a triangle, whereas a real pyramid built by ancient Egyptians has a square base.
How do you find the edges of a graph?
Assume, graph have (n – 1) vertex. The number of edges are given by a function f (n). When you add the nth vertex, you added (n – 1) new edges. A complete graph is a graph in which for every two vertices there is a path between them.
How many faces edges and vertices does a pyramid have?
Pyramids. Pyramids are made up of 5 faces (4 are triangles, 1 is a square). When you join the faces together, it becomes a square-based pyramid with 5 vertices and 8 edges!

What are edges of a pyramid?
An edge is a straight line where two faces of a solid shape meet. A square-based pyramid has 8 edges. A square-based pyramid has 5 vertices. A vertex is a point at which two or more edges meet.
