An octadecagon is an 18 sided polygon.
An octadecagon, also called an octakaidecagon, has 18 sides, from the Greek octa-, signifying 8, the connector -kai-, and deca- signifying 10.
The name of a 18 sided figure is an octadecagon or octakaidecagon. As you can see the prefix octa- means 8, and deca- means 10. It has 18 sides and 18 vertices,
The formula for the number of diagonals (that is, lines joining non-adjacent vertices) belonging to any shape is n(n-3)/2. Therefore, an eighteen-sided polygon has 18 x (18 - 3)/2 = 135 diagonals.
