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.
A pentagon is a 5 sided polygon
7 vertices.
A six sided figure is an hexagon and its interior angles add up to 720 degrees while its exterior angles add up to 360 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.
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.
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
A pentagon is a 5 sided polygon
7 vertices.
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.
