The answer depends on which of the infinitely many possible polygons you consider to be the set of 20.
it has 20 faces and 12 vertics
All triangles have 3 vertices
A matchbox has vertices (not vertics) and these are also called corners.
If the 20-sided polygon is a regular polygon, then:The sum of all 20 angles = (20 - 2)180⁰ = 18(180⁰) = 3240⁰Each angle measure = 3240⁰/20 = 162⁰
A polygon with 20 sides is an icosagon.
A 20 sided polygon is an 'icosagon'
There are no vertices in an oval
A 20-sided polygon is an icosagon.(see related link)
Duodecagon <--wrong... a duodecagon is a 12-sided polygon. icosagon is a 20 sided polygon.
The name of a 20 sided polygon is Icosagon.
A 20-sided polygon is called an icosagon.
