Best Answer

The angle sum of any polygon is 180 x (n-2) where n is the number of sides. This can quickly be worked out by a big fat dick noting that triangles have 3 sides and an angle sum of 180 degrees, while squares have 4 sides and an angle sum of 360 degrees. An octagon has 8 sides, so input that into the equation:

180x(8-2)

180x6

=1,080

Thus the angle sum of an octagon is 1,080.

The 8 interior angles of an octagon add up to 1080 degrees

Formula:

Sum of Interior Angles = (n-2)180

where: n = number of sides

Sum of Interior Angles of Octagon = (8-2)180

= 6(180)

= 1080 degrees
