It is not the number of sides that matters, but the fact that either the sides, or the angles, are not all equal.
No. An irregular polygon is a polygon whose sides are pretty much out of control. They are usually not equal to any other one side. So, no, a star is actually a REGULAR polygon.
A polygon is a shape with 3 or more sides therefore a 2 sided shape isn't a polygon
This can vary. A polygon can have different sides because there are different types. For example, a decagon has 10 ten sides.

No, it does not. You can have a large triangle and a tiny quadrilateral. The first has fewer sides but its perimeter can be much much larger.
I would call it a "ten-thousand sided polygon". Inventing (or memorizing) fancy names for all sorts of polygons, especially those with many sides, really doesn't make much sense.
The answer is N. An n-gon is shorthand for a polygon with n sides.
It will have 55 sides
A pentagon is a 5 sided polygon
The Answers community requires more information for this question. Please edit your question to include more context. The question asks about "this polygon". In such circumstances would it be too much to expect that you make sure that there issomething that "this polygon" refers to?
sum of angles: n=number of sides on the polygon. formula: 180(n-2)
An n-gon is the generic name for a polygon with nsides. It is an especially useful name for a polygon with a number of sides such that giving the polygon a name becomes complicated. For example, calling a shape with 54 sides a 54-gon is much simpler than calling the same shape a pentacontakaitetragon.
