Icosikaihenagon, or also known as Henicosagon.
The term for a 21 sided polygon is an icosikaihenagon. Icosi is the Greek for the numerical 20 and henagon means 1.
An icosikaihenagon is a polygon with 21 sides. The term is derived from Greek, where "icosi" means twenty, "kai" means and, and "henagon" means one, indicating the shape has 20 plus 1 sides. It is a rare shape in geometry and is often discussed in mathematical contexts involving polygons and their properties.
The sum is 3420 as the equation for every regular polygon is (n-2)*180 when n is number of sides
Oh, dude, a 21-sided polygon is called a icosikaihenagon. Yeah, I know, it sounds like something you'd make up after a few too many drinks at a math convention. But hey, that's the beauty of geometry - it's like a party where all the shapes get together and have a good time.
This is a 21 sided polygon and therefore has 21 angles. NOTE : The name supplied for this polygon is an artificial name and never used in practice. General usage refers to this shape as a 21-gon.
Well, honey, a 25 sided polygon is called a "icosikaihenagon." Yes, it's a mouthful, just like your nosy neighbor's gossip. So next time you need to impress someone with your geometry knowledge, just drop that bombshell of a word and watch them squirm.
