an edge
The edge.
That would be an edge.
The solid where two faces meet is called a "polyhedron." A polyhedron is a three-dimensional shape that consists of flat polygonal faces, straight edges, and vertices. Each point where two faces come together is called an edge, and the points where edges meet are called vertices. Examples of polyhedra include cubes, pyramids, and tetrahedra.

an edge or in more simpler term "side"
were two or more faces of a solid figure
As long as they are not parallel, they will meet at an "edge", which is just a straight line.
A vertex is the name of a corner on a solid where three or more faces meet (plural = vertices).
They meet at an edge
If the faces are flat, it's a line.
