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.
