To construct the name of a regular polygon with anything between 20 and 100 sides, a prefix is added to indicate the number of tens, the fragment -kai- to indicate continuation of the name, and a second part of the shape name to indicate the number of units in the shape, before the word -gon, deriving from the Greek word for "angle"
In this case, tetraconta- is the prefix used for the number 40, and di is the fragment concerning the number 2. Therefore, a tetracontakaidigon is a shape with 42 sides.

A 42-sided polygon.
tetracontakaidigon
It is called a tetracontakaidigon.
It is a 42 sided polygon and has: 0.5*(422-(3*42)) = 819 diagonals
a crescent has 19 sides
how many sides does an polygonshave
