How big of an angle do you need to make an octagon?
As long as your shape has eight sides, angles of smaller or greater size than 135 o can be used, resulting in an irregular octagon. The exception to this rule is for angles of exactly 180 o. Generally, the two line segments that make up such an angle can be considered a single edge in a polygon. 3
Is there such a thing as a regular octagon?
It bears mentioning that, though people commonly use the word “octagon” to refer to a regular octagon (one with sides and angles that are the same size), this is not, strictly speaking, the only kind of octagon that exists. Any shape with eight sides is an octagon by definition, just not a regular octagon.
