Exterior angle: 45 degrees Interior angle: 135 degrees

Each interior angle measures 135 degrees Each exterior angle measures 45 degrees

Each interior angle is 150 degrees

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.

An interior angle of a dodecagon is 150 degrees. An interior angle of an octagon is 135 degrees. So the angles of 2 dodecagons and 1 octagon would sum to 435 degrees. A point in the plane has 360 degrees around it. Angles that sum to 435 degrees would, therefore, result in overlap.

I am going to assume that you mean a regular octagon. If you use the formula 180(n-2), where n=the number of sides, plug in 8 for an octagon and you get 1080 as the sum of the interior angles. Now divide this by 8 in order to get the measure of one of the interior angles, which turns out to be 135. Now, if you are looking for the exterior angle measurement, then simply subtract 135 from 180 to get 45. 45 is your exterior angle measurement, 135 is your interior angle measurement.

Each interior angle is 162 degrees.
