An edge is the the answer
A vertex is the name of a corner on a solid where three or more faces meet (plural = vertices).
Dodecahedron.
A solid figure that has some of the same faces but some different faces, and has one more face than the other, is a prism and a pyramid. A prism has two identical bases and rectangular or square faces, while a pyramid has a polygonal base and triangular faces that meet at a single point, called the apex. The prism has one more face than the pyramid.

In geometry and trigonometry, an angle (in full, plane angle) is the figure formed by two rays sharing a common endpoint, called the vertex or vertex of the angle (vertices in plural).With solid figures, like pyramids or polyhedrons, a vertex is a corner where three or more of the faces meet.Remember,* faces are the flat sides.* Edges are the lines where two of the faces meet.* Vertices are the corners where three or more of the faces meet.
triangular prisum
a rectangular pyramid and a square pyramid
A polyhedron is a solid figure with many plane faces, typically more than six.
