Where two faces meet on a 3D figure is called an edge. An edge is the line segment that connects two vertices, which are the points where the faces intersect. In polyhedra, edges play a crucial role in defining the shape and structure of the figure. Each edge is shared between two adjoining faces, contributing to the overall geometry of the solid.
An edge is an area of a 3D figure where two faces meet to form a line segment.

There are two 3D shapes with five faces: Triangular prisms and rectangular pyramids.
They are the sets of points (or lines) where two faces meet.

Since a face of a 3d figure is the same as a side, you have two faces sharing a face! The result is lots of coincident faces!
