An octdecagon is a polygon with 18 sides and 18 vertices. The term is derived from the combination of "octo-" meaning eight and "decagon" meaning ten, reflecting its total of 18 sides. In geometry, it is classified as a convex polygon if all its interior angles are less than 180 degrees. Octdecagons are less commonly referenced than polygons with fewer sides, but they follow the same principles of polygonal geometry.
What else can I help you with?
What is the measure of each of the interior angles of a regular 18 gon?
Interior angles of a regular 18 gon (octdecagon) are 160o.
What regular polygon has a 160 degree angle?
A regular octdecagon (18 sided geometric figure) was internal angles of 160 degrees.
What is the measure of each interior angle of a 18 sided regular polygon?
The interior angle of an octdecagon, an 18 sided regular polygon, is 160o.
What is a 10 or more sided polygon called?
10 - Decagon 11 - Hendecagon 12 - Dodecagon 13 - Triskaidecagon or Tridecagon 14 - Tetraidecagon or Tetradecagon 15 - Pendecagon 16 - Hexdecagon 17 - Heptdecagon 18 - Octdecagon 19 - Enneadecagon 20 - Icosagon Occasionally, Mathmaticians will refer to these as n-gons. So a 17 Sided Polygon could just be called a 17-gon.
