Octagon has 8 sides
So sum of angles = 8 x 180° - 360° = 1080°
the sum of the angle in a octagon is 1080
For a regular octagon it is 1080

An octagon is a 8-sided polygon. Sum of interior angles of octagon = (8 - 2) x 180o = 1080o
Any measure that you like. There are no restrictions on an angle of an octagon, only on their sum.
1680
(8-2)*180=1080
360 degrees
The 8 interior angles of an octagon add up to 1080 degrees.
