Angles are measured in degrees, not sides.
Interior angle: 135 degrees Exterior angle: 45 degrees
Each exterior angle 45 degrees Each interior angle 135 degrees
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.
Angles are supplementary if they add up to 180. So, with some algebra 45+x=180 x=180-45=135
