I am trying to find the interior and exterior angles of a 9 sided polygon .
The exterior angles are 360/9 = 40 degrees, (if the polygon is regular.. all lengths and sdes equal).
The interior angles are 180 - 40 = 140 degrees.
To find the interior and exterior angles of a polygon, we can use the formulas:
Interior angle = (n - 2) * 180 / n
Exterior angle = 360 / n
Where "n" represents the number of sides of the polygon.
In this case, you have a 9-sided polygon, so let's plug in the value of "n" into the formulas.
Interior angle = (9 - 2) * 180 / 9
Interior angle = 7 * 180 / 9
Interior angle = 1260 / 9
Interior angle = 140 degrees
Exterior angle = 360 / 9
Exterior angle = 40 degrees
Therefore, the interior angle of a 9-sided polygon is 140 degrees, and the exterior angle is 40 degrees.
