A polygon is made up of straight line edges between its vertices. There are the same number of edges as vertices in a polygon.
In the case of a polygon, it is convex if all interior angles are less than 180o.
There are no curved edges in a pentagon. Part of the definition of any polygon is that they have straight edges.
it has 0 curved edges
it has 0 curved edges
An egg typically does not have defined edges like a polygon or a polyhedron because it is a smooth, oval shape known as an ovoid. Instead of edges, it has a continuous curved surface. Therefore, in geometric terms, an egg has no edges.
The answer depends on the number of sides in the polygon.
There are no curved edges, but it does stack.
there are no curved edges on any triangle.
There are no curved edges on a triangular pyramid.

In 3 dimensions, at least, a cube has no curved edges.
A cylinder has two curved edges, which are the edges where the curved surface meets the two circular bases. In addition to these curved edges, a cylinder also has two flat circular faces but no sharp edges.
there are 4 edges
