As long as they are not parallel, they will meet at an "edge", which is just a straight line.
If the faces are flat, it's a line.

That would be an edge.
Edge. (:
An edge is the the answer
That would be an edge.
An angle is formed at the vertex
Technically, that's known as an "edge" of the prism.
An edge is an area of a 3D figure where two faces meet to form a line segment.
