That would be classified as an edge.

A polyhedron that has two congruent faces is called a prism. It means that when it is cut at the cross-section, the shape is the same as its base.
They are faces the polyhedron.
A spherical polyhedron is a dodecahedron with 12 faces

EDGE
An edge.
Two faces of a polyhedron form a wedge-shaped segment in three dimensional space.
The faces of a three-dimensional object meet at edges. An edge is the line segment where two faces intersect, forming a boundary between them. In a polyhedron, for example, these edges connect the vertices of the object, defining its shape and structure.
They are the faces of the polyhedron.
The line segments that are common to intersecting faces of a polyhedron are called edges. Each edge is formed by the intersection of two faces and serves as a boundary between them. In a polyhedron, edges connect the vertices and help define the overall shape of the three-dimensional figure.
A polyhedron with 20 faces is called an icosahedron.
The place where two faces (planes) intersect is called an edge.
A Prismthe faces are called bases
