Curved, the edge is the on the opposite side of the tip.
a cylinder
yes, they are the 2 straight lines
The geometrical object known as a cone has no planar faces, two curved surfaces, no edges and one vertex. A "real" object often called a cone is a portion of a half cone. That has one base, a curved surface, and one vertex.

There are no curved edges in a pentagon. Part of the definition of any polygon is that they have straight edges.
Curved, the edge is the on the opposite side of the tip.
No, all 6 edges of a hexagon are straight
