Given: ABCDEFGH is a regular octagon; diameter (diagonal) = d
Let the side length of the octagon be s.
Label with O the intersection of the diagonals.
Look at the formed isosceles triangle AOB.
Draw the apothem OK, which is also the altitude of the triangle AOB, which bisect the side AB.
Look at the right triangle AOK. Here we have:
The length of AK is s/2.
The length of AO is d/2.
The angle A is 67.5° (135°/2)
So that,
cos 67.5° = (s/2)/(d/2)
.383 = s/d
(.383)d = (s/d)(d)
(.383)d = s
Thus, the side length of the octagon equals (.383)d.

Assuming that the perimeter of the regular octagon is 32 inches, and since it has 8 sides, then the length of one side of the figure is 32/8 or 4 inches.
An octagon is an eight-sided figure. If a regular octagon has a perimeter of 24 inches, then each side will be 24 / 8 = 3 inches.
920 mm. Because since an octagon has 8 sides and they are all 115 in length, to find the total perimeter simply add up 115 8 times, or multiply 115 by 8.
An octagon is a polygon with 8 sides. To find the diameter of a regular octagon when each side is 18 inches in length, you can use the formula: Diameter = Side length × √(2 + √2) Plugging in the given side length (18 inches): Diameter = 18 × √(2 + √2) ≈ 56.97 inches So, the diameter of the octagon is approximately 56.97 inches.
a regular octagon has the same length all sides. so with the given angle draw 8 sides at an angle of 135 degrees from each other
The diameter of an octagon with sides of 11 feet can take any value between 0 feet and 44 feet.
Since the diameter is 48 inches, and there are 8 sides, then each side will be 48/8 = 6 inches.
Octagon just means it has 8 sides. Regular octagon means it has 8 sides of the same length and the angles are equal.
They can be. A regular octagon has all sides of equal length.
I think the diameter is 58"
An octagon has eight sides. A regular octagon is one that has eight sides of equal length, and all the angles are of the same measure. Anything else - sides that are not all the same length, or not all angles the same - would be a non-regular octagon.
An irregular octagon has eight sides, but they aren't all of equal length
An octagon is any figure that has 8 sides, no one said that all of the sides had to be the same length.
It depends how long each side is. An octagon's sides do not have to all be the same length, they can vary from octagon to octagon. A regular octagon's sides are all equal so the sum of their measures would be 8 times the length of any one side..
An octagon that is not irregular is a regular octagon, one in which each of the eight sides os the same length
