Shapes with 13 to 20 sides are known as polygons. Specifically, a 13-sided polygon is called a tridecagon, a 14-sided polygon is called a tetrakaidecagon, a 15-sided polygon is called a pentadecagon, a 16-sided polygon is called a hexadecagon, a 17-sided polygon is called a heptadecagon, an 18-sided polygon is called an octadecagon, a 19-sided polygon is called an enneadecagon, and a 20-sided polygon is called an icosagon.

18. If a polygon has n sides, then it has n-2 triangles.There are 18 triangles in a 20 sided polygon.
An 18 sided polygon is called a Octadecagon or a Octakaidecagon
The interior angle of an octdecagon, an 18 sided regular polygon, is 160o.

If you say this shape is 18 sided i would guess it has 18 sides. ;)
