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 edges on a cone
A cone has a curved base edge and 1 vertex

Both.
There are no curved edges in a pentagon. Part of the definition of any polygon is that they have straight edges.
Cone
Curved, the edge is the on the opposite side of the tip.
A cone has one face - its base - and one edge but no vertices. Vertices only occur at the meeting of two straight surfaces.
No, all 6 edges of a hexagon are straight
They are straight lines where two plane faces of the shape meet. The definition is sometimes extended to curved lines where curved (3d) faces meet such as at the base of a cone.

A cone has either one or two surfaces and either one or no edges.
