It has 18
An octadecagon is an 18 sided polygon.
An octadecagon has 18 sides. To find the sum of the interior angles of a polygon, you can use the formula ((n - 2) \times 180), where (n) is the number of sides. For an octadecagon, the sum of the interior angles is ((18 - 2) \times 180 = 2880) degrees. Each interior angle of a regular octadecagon is (2880 \div 18 = 160) degrees.
The name of a 18 sided polygon is Octadecagon.

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.
