Interior degrees add up to 1080 degrees Exterior degrees add up to 360 degrees
A 9 sided polygon is a nonagon Its exterior angles add up to 360 degrees Its interior angles add up to 1260 degrees --------------------------------------------------------- Also the sides of a nine sided figure can not be sold separately.
7 vertices.
A pentagon is a 5 sided polygon
The internal (inside) angles of any regular polygon are equal to (n - 2) x 180, where n is the number of sides in the polygon. For example, the sum of the internal angles inside a six-sided shape (hexagon) are equal to (6 - 2) x 180 = 720 degrees.To find out how much each angle measures, simply divide the result of this by the number of sides - so, 720 / 6 = 120 degrees. Each internal angle in a hexagon is equal to 120 degrees.
Interior degrees add up to 1080 degrees Exterior degrees add up to 360 degrees
A 9999-sided polygon is known as a nonanonacontanonactanonaliagon. Unlike a 9999-sided polygon, a 10000-sided polygon has a much easier name; a myriagon.

Like all polygons the exterior angles add up to 360 degrees
A polygon is a shape with 3 or more sides therefore a 2 sided shape isn't a polygon
By 900 degrees as for example a triangle has 3 sides that add up to 180 degrees then if 5 sides are added to it then it then is an 8 sided octagon with interior angles that add up to 1080 degrees
7 vertices.
A pentagon is a 5 sided polygon
A seven sided shape need not cost you anything!
I suggest you just call it a "373839-sided polygon". Inventing, memorizing, or deriving fancy names is too much trouble for such large numbers.
180
On an ordinary shhet of paper, very much like a circle.
