It need not have any.
How many parallel sides has a trapezium?
0 Parallel sides
It Has 2 Pair of Parallel Sides
It has three parallel sides. ;)
Well, honey, a shape with 20 sides is called an icosagon. It's like a polygon on steroids, with all those sides flaunting their angles like they're on a runway. So next time you need to impress someone with your geometry knowledge, just drop the word "icosagon" and watch them swoon.
20 sides
Twenty.
It is not a solid figure because an icosagon is a polygon with 20 sides
An icosagon has just one flat face because it is a polygon that has 20 sides
An icosagon is a two-dimensional polygon, not a three-dimensional figure. An icosagon has 20 sides - while an icosahedron has 20 faces.
20 sides and 170 diagonals

An icosagon is a polygon with 20 sides and 20 angles. Each internal angle of a regular icosagon measures 162 degrees, while the external angle measures 18 degrees. The sum of the internal angles of an icosagon is 3,240 degrees. Additionally, an icosagon can be regular (all sides and angles equal) or irregular (sides and angles of varying lengths).
It is icosagon.it mostly look like a circle
