A polygon has as many vertices as it has sides and so in this case it will have 20 vertices.
Duodecagon <--wrong... a duodecagon is a 12-sided polygon. icosagon is a 20 sided polygon.
A 20-sided polygon is an icosagon.(see related link)
18. If a polygon has n sides, then it has n-2 triangles.There are 18 triangles in a 20 sided polygon.
The name of a 20 sided polygon is Icosagon.

20 of them.
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.
An icosagon is a 20 sided polygon that has 20 vertices which is the plural of vertex
There are many options. Some of these are: A pyramid with a base that is a 19 sided polygon; A dipyramid with a "centre" that is an 18 sided polygon; A prism with decagonal bases.
It has 20 vertices.
20

To calculate the number of triangles that can be formed by connecting the vertices of a 20-sided polygon, we can use the formula n(n-1)(n-2)/6, where n is the number of vertices. For a 20-sided polygon, n = 20, so the formula becomes 20(20-1)(20-2)/6 = 1140. Therefore, you can fit 1140 triangles within a 20-sided polygon.
