An octagon has interior angles of 1080 degrees.
octagon
the sum of the interior angles of a polygon is 180(n-2), where n is the number of sides.1080 = 180(n-2)6 = n-2n = 8The polygon has 8 sides, it is an octagon.
The sum of the interior angles of a polygon is 2n - 4 right angles - where n is the number of sides. So, 1080° = 1080/90 = 12 right angles If 2n - 4 = 12 then 2n = 16 : n = 8 The number of sides is 8.

octagon
The sum of the interior angles in a polygon with n sides is 180º(n-2). That means that for an octagon, the answer is 180(8-2) = 180(6) = 1080. The sum of the inside angles is 1080 degrees.
The 8 interior angles of an octagon add up to 1080 degrees
If the polygon has n sides, the sum of its interior angles is 180*(n-2) = 1080 So n-2 = 1080/180 = 6 And therefore n = 8
The interior angles of an octagon add up to 1080 degrees
