A polygon has the same amount of vertices as it does sides, so it would have 7 vertices.
Polygons have the same number of vertexes/vertices as the sides. So, A 20 sided polygon will have 20 vertexes/vertices.

A shape with four sides and three vertices does not exist in Euclidean geometry. In Euclidean geometry, a shape must have the same number of sides as vertices. Therefore, a shape with four sides would have four vertices.
Polygons are 2D plane figures. All polygons with 7 sides would be classified as heptagons.

Not all shapes are polygons. Polygons are shapes that have to have straight sides and be closed figures. So a shape that is curved would not be a polygon.
it depends how many sides it has so, for e.g. if it is a octagon it would have 8 vertices because an octagon has 8 sides.
There are infinitely many polygons so it would be impossible to name them all. For the names of those with a fewer sides see the related link.
Anythings that are concentric share the same "center". In this case, regular polygons (mostly) have a point in their interior that is the same distance from each of its vertices ("corners"). Concentric polygons would all have the same center point.
All regular polygons, from an equilateral triangle upwards. Aslo, all regular polygons with 4 or more sides can be squashed or distorted but they would still have sides of equal length.
The majority of polygons would meet these requirements. Polygons with congruent sides are the exception rather than the other way around.
A polygon has as many vertices as it has sides and so in this case it will have 20 vertices.
