Only a regular octagon will have 8 equal sides.
A regular octagon's angles and sides are all the same. As in the angles are the same, and the lengths of each side are the same. And irregular is basically the opposite of that.
By using the definition of "perimeter": you need to add the lengths of all eight sides. If it is a REGULAR octagon, you multiply the length of any side by 8, since all sides have the same length.
You say these things to yourself: -- "The perimeter is the distance all the way around the octagon." -- "The octagon has eight sides." -- "So, if it's a 'regular' octagon, then all the sides are the same length, and each side must be 1/8 of the perimeter." -- If it's not a 'regular' octagon, then it has some longer sides and some shorter ones, and the perimeter doesn't help me find the lengths of the sides.
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..
The perimeter of an octagon is the distance around its outside, so it is the sum of the lengths of each of its eight sides.
yes
its the same as all other side lengths
An octagon can be either regular or irregular. A regular octagon in a 2-dimensional closed figure with eight sides, all of which are the same length. This means that all the angles are the same, too. An irregular octagon is a 2-dimensional closed figure with eight sides, but at least two of the sides are of different length. All sides can be of different lengths.
A pentagon has five side and the lengths do not all have to be the same, apentagon which ahs all five side the same is sometimes called a "true pentagon"
Only if they are congruent triangles
112 inches, that is if all the sides are the same length .I think.
