The sum of the interior angles of any regular polygon of n sides is equal to 180(n - 2) degrees. 1260 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

The interior angles of a nonagon add up to 1260 degrees

The answer depends on what elements of a nonagon you measure.
