It depends on how many sides it has...
The interior angles of a polygon (regular or not) with n sides sum to (n - 2)*180 degrees.
The 8 interior angles add up to 1080 degrees
Exterior angles add up to 360 degrees Interior angles add up to 1440 degrees
The total interior angles add up to 1260 degrees.
Its 5 interior angles add up to 540 degrees
you add the other 3 internal angles together and take the answer away from 180 and the number that is left is your answer.
It is a regular 9 sided polygon whose 9 interior angles add up to 1260 degrees
The interior angles of a polygon (regular or not) with n sides sum to (n - 2)*180 degrees.
-- The exterior angles of a polygon add up to 360 degrees, no matter how many of them there are.-- The interior angles of a polygon add up to [ (180) times (number of sides minus 2) ].-- These are both true whether or not the polygon is 'regular'.
The interior angles add up to 1080 degrees
