The interior angles would ad to (9 - 2)*180 = 7*180 = 1260 degrees.
A 9 sided polygon is a nonagon Its exterior angles add up to 360 degrees Its interior angles add up to 1260 degrees --------------------------------------------------------- Also the sides of a nine sided figure can not be sold separately.
A nine sided polygon is called a "nonagon"

A 9 sided nonagon has 9 interior angles that add up to 1260 degrees

The sum of the interior angles of a nonagon is 1260 degrees. A nonagon is a nine-sided polygon in geometry. The formula to find the sum of interior angles in a polygon is given by the formula [n-2] x 180 degrees, where n represents the number of sides.
nonagon- nine-sided polygon
If this 9 sided polygon is a regular polygon, then the sum of its angles is:(n - 2)180 degrees = (9 - 2)180 degrees = 7 x 180 degrees = 1,260 degrees.
a nonagon is the name given to a nine sided polygon
do you mean Nonagon. It is a nine sided polygon, edges and vertices - 9, internal angles 140o
1260/9 ie 140 degrees assuming polygon is regular. Total is not affected by regularity.
