What is the name of a 17 sided shape?

The names of the sided shapes as mentioned above are as follows: A 17 sided shape is called a heptadecagon or a heptakaidecagon. This is part of the polygon shapes. A 20 sided shape is called an icsoagon.

What is the name of a polygon with 17 sides?

A polygon with 17 sides is known as Heptadecagon or Heptakaidecagon, polygon with 18 sides is known as Octadecagon or Octakaidecagon, polygon with 19 sides is called Enneadecagon or Enneakaidecagon and a polygon with 20 sides is named as Icosagon. I hope this information will work for you.

What is the difference between a 19 sided shape and Polygon?

A 19 sided shape is called an enneadecagon (pronounced en-ee-deck-uh-gon) 20 sided shape; A 20 sided shape is called an icsoagon. All of these shapes are from the polygon family. A polygon simply means that it is a shape that is bounded by a closed path or circuit, which is made up of a sequence of straight lines or edges.
