To calculate the sum of the angels of an octagon follow the given steps:

Sum of interior angles = 180(n - 2)

The above given is the formula to find the sum of the interior angles of a polygon and an octagon is a polygon with eight sides. Now, applying the same formula you will get,

Sum of interior angles = 180(8 - 2) = 1080

Sum of interior angles = 180(n - 2)

The above given is the formula to find the sum of the interior angles of a polygon and an octagon is a polygon with eight sides. Now, applying the same formula you will get,

Sum of interior angles = 180(8 - 2) = 1080
