the sum of the angles in a polygon = the number of sides n less 2 x 180, or (n-2)*180. so the answer to the Q is as follows
1080 = 180*(n-2); n = 2+ (1080/180)
An octagon has interior angles of 1080 degrees.
The 8 interior angles add up to 1080 degrees
The interior angles of any polygon add up to the number of sides - 2, times 180 degrees. For an octagon this is 180 x 6 with is 1080 degrees, thus: The sum of the interior angles of a regular octagon is 1080 degrees
Total angles: (8-2)*180 = 1080 degrees Each interior angle: 1080/8 = 135 degrees
The interior angles of an 8 sided octagon add up to 1080 degrees
The interior angles of an octagon add up to 1080 degrees
An octagon has interior angles of 1080 degrees.
The 8 interior angles add up to 1080 degrees
Because it has eight sides it is an octagon so:- Exterior angles: 360 degrees Interior angles: 1080 degrees
8
The interior angles of an 8 sided octagon add up to 1080 degrees
8
If the polygon has n sides, the sum of its interior angles is 180*(n-2) = 1080 So n-2 = 1080/180 = 6 And therefore n = 8
The interior angles of any polygon add up to the number of sides - 2, times 180 degrees. For an octagon this is 180 x 6 with is 1080 degrees, thus: The sum of the interior angles of a regular octagon is 1080 degrees
Total angles: (8-2)*180 = 1080 degrees Each interior angle: 1080/8 = 135 degrees
By 900 degrees as for example a triangle has 3 sides that add up to 180 degrees then if 5 sides are added to it then it then is an 8 sided octagon with interior angles that add up to 1080 degrees
8 sides
