I want to say 2, once at each corner
Each point of a polygon at which two sides intersect is called VERTEX
It simply means that the angle at each corner is exactly the same as its neighbour.
It is called a face of the polyhedron.
Each point is called a vertex.
I think you mean corner and it's called a vertex. If you have more than one vertex they are called vertices.
