The external angle of a polygon is equal to 360/n, n representing the number of sides in the polygon. Since an octagon has eight sides, the external angle of a regular octagon is 360/8 = 45 degrees.
Since a straight angle in a polygon would be equal to 180 degrees, you subtract the measure of the external angle from this, to make an internal angle of 180 - 45 = 135 degrees.

What is angle measures of an octagon?
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.
What are the measurements of each angle in a regular octagon?
If you cut a regular octagon into triangles, it would be 6 triangles. the measurement of all the angles in a triangle added up are 180 degress multiply 6x180=1080 the measurement of all the angles in a octagon added up are 1080 degress there are 8 angles in a octagon. divide 1080 by 8=135 135 degress in each angle in a regular octagon
