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

The 8 interior angles of an octagon add up to 1080 degrees.
360 degrees
To find interior angle measurements, you must divide the shape into triangles by drawing diagonal lines. The diagonal lines draw triangles, and the interior angle measure of triangles are always 180 degrees. The sum of interior angles of an octagon is 1080 degrees. How ever many triangles you have, multiply it by 180. See octagons in the link for more help,
1080 degrees
sum interior angles = (number of sides - 2) × 180°= (8 - 2) × 180°= 1080°The sum of the interior angles of an octagon is 1080°In a regular octagon, divide by 8 for each angle = 135°.
360 degrees is the interior angle for anything that is enclosed.
Any measure that you like. There are no restrictions on an angle of an octagon, only on their sum.
The 8 interior angles of an octagon add up to 1080 degrees.
It is: (8-2)*180 = 1080 degrees
