Best Answer

45 degrees, for the adjoining angles of the straight edges. Otherwise, the straight edges would be 180 degrees and 90 degrees.

an octagon (8-sided)

It is a regular 8 sided octagon

Interior angle: 135 degrees Exterior angle: 45 degrees

If it is a regular 8 sided octagon then each interior angle is 135 degrees

For any REGULAR n-sided polygon the interior angles are (180 - 360/n) degrees eg for a regular octagon, where n = 8, the calculation is 180 - 360/8 ie 180 - 45 = 135o degrees.
