Yes. I think of an edge as a line. The edges meet at vertices, and the faces meet at edges.
If the faces are flat, it's a line.
I'm waiting for the answer
an edge or in more simpler term "side"
a cone * * * * * That cannot be correct. The apex of the cone is a vertex. I do not believe that such a shape is possible. Wherever the two faces meet, there will be an edge.
As long as they are not parallel, they will meet at an "edge", which is just a straight line.
were two or more faces of a solid figure
They meet at an edge
It's called a point.
The edge is a line - straight or curved - where two faces of the solid meet.
