An irregular octagon.
I would call it an irregular octagon, or an irregular 8-sided polygon.
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.
Yes, an octagon is a polygon that has eight sides.
an octagon is a polygon. an octagon has 8 sides. a polygon is a shape with closed sides.
An octagon is a two-dimensional polygon with eight sides which can be regular or irregular

No. An octagon is an 8 sided polygon. The only rigid polygon is a triangle.
Polygons can either be regular or irregular. A regular polygon is for example a octagon which has sides and angles that are all the same. Irregular they are not all the same.
If the octagon is a regular octagon (all eight sides and all eight angles are equal), then it is a regular polygon. If it is not a regular octagon (i.e. if it is an irregular octagon) then is it an irregular polygon.
An irregular octagon.
There are actually several lines of symmetry for a regular octagon. An irregular octagon could have fewer.
Assuming you cut it at the angles, the answer is " A Polygon" of 5 sides, also called an irregular pentagon. If you were to cut the octagon along the straight lines, the answer would still be a polygon but then it would have 6 sides and be called an irregular hexagon. For example, cutting a stop sign vertically down the middle would give you a six sided polygon.
Simply that: "irregular octagon".
