An irregular octagon.
I would call it an irregular octagon, or an irregular 8-sided polygon.
Yes, a regular polygon has all sides of equal length. An irregular polygon is any polygon that is not regular.
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.
An octagon is a two-dimensional polygon with eight sides which can be regular or irregular
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.
No. An octagon is an 8 sided polygon. The only rigid polygon is a triangle.
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.

There are actually several lines of symmetry for a regular octagon. An irregular octagon could have fewer.
an irregular polygon is a polygon that is the opposite of a regular polygon in a regular polygon the sides are the same and the angles are the same and irregular is the opposite.
A polygon with eight sides, regular or not, is an octagon. There isn't a special name for a regular octagon (other than "regular octagon").
It is an octagon.
