Each angle is 45 degrees - eight 45 degree angles equals 360 degrees.
Providing that it is a regular octagon then each interior angle will measure 135 degrees
The interior angle measurement of an octogon is 1080 degrees. Each angle is 135 degrees.
It is a regular 8 sided octagon
360/8 = 45 degrees.
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

The interior angle measurement of an octogon is 1080 degrees. Each angle is 135 degrees.
The total angle measurement is 720 degrees.

you say dik and u shake it all about that's how you dik about
It is: 1080 - 835 = 245 degrees
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.

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.
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.
The angle on a straight line is 180° .
