A 102-sided polygon is called a hectaicosagon. It is a polygon with 102 sides and 102 angles. The sum of the interior angles of a hectaicosagon can be calculated using the formula (n-2) x 180 degrees, where n is the number of sides. In this case, the sum of the interior angles of a hectaicosagon would be (102-2) x 180 = 18000 degrees.
It's perfectly acceptable to call it an 102-agon but what's more important is knowing how to work out its properties.
A five sided polygon is called a pentagon because pentagon means five sided polygon I think.
An 11 sided polygon is a hendecagon and a 12 sided polygon is a dodecagon
icosihenagon= 21-sided polygon icosihenagon= 21-sided polygon
The name of a 12 sided polygon is Dodecagon.
Hectodigon
Remember the two equations. Exterior angle = 360 / no. of sides. Interior angle = 180 - exterior angle. So for 102 sided polygon. exterior angle = 360/102 = 3.5294... Interior angle = 180 - 3.5294... = 176.4706.... Hence sum of the 102 sided polygon's angles is 102 X 176.4706 = 18,000 degrees. ( to nearest degree).
It's perfectly acceptable to call it an 102-agon but what's more important is knowing how to work out its properties.

Duodecagon <--wrong... a duodecagon is a 12-sided polygon. icosagon is a 20 sided polygon.
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.
