A 20-sided polygon is called an icosagon. In geometry, a polygon with n sides has n vertices. Therefore, a 20-sided polygon would have 20 vertices. Each vertex represents a point where two sides of the polygon intersect.

20, because a polygon has the same number of sides and vertices.
A polygon has the same amount of vertices as it does sides, so it would have 7 vertices.
Twelve. The number of sides and vertices in a polygon are always the same.
it has 12 vertices
It has 20 vertices.
A polygon has as many vertices as it has sides and so in this case it will have 20 vertices.
20, because a polygon has the same number of sides and vertices.

19. sides=vertices
Twelve. The number of sides and vertices in a polygon are always the same.
A 6 sided polygon is an hexagon which has 6 vertices
it has 12 vertices
It has 20 vertices.
12 sides, 12 angles, 12 vertices
Fourteen. Each polygons has the same number of sides as it has vertices. Therefore, a polygon with 14 vertices must have 14 sides.
A polygon has the same quantity of vertices as it has interior angles.
a hexagon, and it has 6 vertices
