180-135 = 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.
obtuse
the completment of a 65 degree angle is 130
The supplement of 45 degrees is 135 degrees.
Each of the internal angles on a regular octagon measures 135 degrees.
The number of sides of a regular polygon is 360 divided by the size of the exterior angle. The external angle is 180 - the internal angle. So for a regular polygon with an internal angle of 135 we get the following. 360 / (180 - 135) = 360 / 45 = 8 sides
Do 180-135 and you will get your answer.
right
Cut a 45 degree angle "going the other way".
It is: 45 degrees
It is: 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.
As the angle is between 90 degrees and 180 degrees, it an obtuse angle.

I'm not sure but you can just bracket the 135 degree angle by attaching one end to the other and make a wall?
The supplement of an angle is the angle that, when added to the original angle, equals 180 degrees. Therefore, the supplement of a 45-degree angle would be 135 degrees, because 45 + 135 = 180. This relationship holds true for all angles, where the sum of an angle and its supplement is always 180 degrees.
