an octogon is a shape, so it has no sum
it is like asking for the sum of a triangle
the sum of the angle in a octagon is 1080
Sum of interior angles of an octagon= 1080˚
It is the sum of the lengths of the octagon's eight sides.
1080
the sum of the angles is 1080
The sum of the measures of the exterior angles of an octagon (and any polygon) is 360o.
The sum of the interior angles of an 8 sided octagon add up to 1080 degrees
An octagon is a 8-sided polygon. Sum of interior angles of octagon = (8 - 2) x 180o = 1080o
For a regular octagon it is 1080
Sum of angles in a regular polygon = (#sides - 2) * 180. Sum of Octagon angles = (8-2) * 180 = 1080
1080°
The perimeter of a octagon is the sum of all its sides.
