the total measure of a regular octagon is 1080 degrees
8 (measure of each side) x 8 (total sides of an octagon) = 64cm
The interior angles of an octagon add up to 1080 degrees 1080 degrees in total, 135 each.
The measure of the exterior angle of a convex octagon is indeterminate.
An equiangilar octagon is an octagon in which all angles have the same measure. which makes each angle about 45 degrees.
Eight - that is why it is called an octagon.

The measure of the exterior angle of a convex octagon is indeterminate.
An interior angle of a regular octagon is 45 degrees. The exterior angles measure 315 degrees.
An equiangilar octagon is an octagon in which all angles have the same measure. which makes each angle about 45 degrees.
45 degrees providing that it is a regular octagon
Eight - that is why it is called an octagon.
The measure of one of the regular octagon angles of the shape is 135 degrees, regardless of the size of the octagon. This means that the interior angles are all 135.
Individual angles in an octagon can have any measure - anything between 0 and 360 degrees. Only the sum of the angles has to total a certain amount (in the case of the octagon, 6 x 180 degrees). A regular octagon has internal angles of 135 degrees and external angles of 45 degrees.
Any measure that you like. There are no restrictions on an angle of an octagon, only on their sum.
