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 on a triangular pyramid.
there are no curved edges on any triangle.
There are no curved edges, but it does stack.

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
