It is the sum of the lengths of the nine sides of the nonagon.
1260 degrees
The sum of the measures of the interior angles of a heptagon is 900 degrees.
The sum of the four interior angles is 360 degrees.
The sum of the angles should equal 180
The answer depends on what elements of a nonagon you measure.

180 (9-2)=180x7=1260
A nonagon aka enneagon
The interior angles of a nonagon add up to 1260 degrees
The sum of the interior angles of any regular polygon of n sides is equal to 180(n - 2) degrees. 1260 degrees
It is the sum of the lengths of the nine sides of the nonagon.
It is a 9 sided nonagon and its 9 interior angles add up to 1260 degrees
(2 x 9 - 4) right angles = 14 x 90 = 1260 degrees
