There is no such thing as a nanogon. However, there is a geometrical figure called a nonagon. An interior angle of a nonagon can have any value between 0 and 360 degrees (except 180); the only restriction is that the sum of all nine interior angles of a nonagon is 1260 degrees.
There is no regular polygon with an interior angle of 20o. If the interior angle is 120o then there are six sides and the sum of the angles is 720o.
1260 degrees
It is a 9 sided nonagon and its 9 interior angles add up to 1260 degrees
The interior angles of a nonagon add up to 1260 degrees

1260 degrees
(2 x 9 - 4) right angles = 14 x 90 = 1260 degrees
The sum of the interior angles of any regular polygon of n sides is equal to 180(n - 2) degrees. 1260 degrees
360 degrees
The sum of the interior angles of a nonagon is (9 - 2) x 180o = 7 x 180o = 1260o In a regular nonagon, each interior angle is 1260o ÷ 9 = 140o
Interior angles = 1260 degrees Exterior angles = 360 degrees
