8 if it's an regular octagon
Whether it is a regular or irregular octagon does not matter. An octagon is, by definition, a 2-dimensional figure with eight sides, and therefore with eight angles. A regular octagon will have eight equal angles and an irregular octagon will have eight angles some of which are not equal to the others.
Assuming that this is a regular octagon, with all of its angles equal, then each of those angles would be 135 degrees.It is 1080 degrees.
In a regular octagon, each angle is 135 degrees. If the octagon is not regular, then it can have as many as 6 right angles in it.
A regular 8 sided octagon has no acute angles but has 8 equal obtuse angle of 135 degrees that add up to 1080 degrees
8 angles
An regular 8 sided octagon has no right angles unless it is shaped into an irregular octagon.
A octagon has 8 angles An octogon has 8 equal angles and 8 equal sides.
The sum of the interior angles of an octagon is equal to 1080 degrees.
A regular octagon has 8 interior obtuse angles.
It depends whether its regular or irregular.
Whether or not a polygon is regular makes no difference to the number of sides or angles that it contains. An octagon has eight sides and eight angles.
