A polygon that has 10 sides that are not all equal
* * * * *
Got the right idea but wrong in the detail. It is a polygon with ten sides in which
Thus a polygon with ten equal sides, and 9 equal angles but the tenth angle being different, would be irregular.
Any polygon is regular if its sides are all the same length, or irregular if they're not. If all 10 sides of your decagon are the same length, then you have a regular decagon. If they're not, then you have an irregular one.
You just call it a decagon. If all the angles and sides are equal then it's a regular decagon. If not, it's an irregular decagon.
An irregular do-decagon
It still has ten sides, same as a normal decagon. "Irregular" simply means that all the sides and angles of the decagon are not congruent.
Not normally but if it was an irregular decagon then it's quite possible.
No if it's an irregular decagon
Any polygon is regular if its sides are all the same length, or irregular if they're not. If all 10 sides of your decagon are the same length, then you have a regular decagon. If they're not, then you have an irregular one.

An irregular decagon
all decagons have 1440 degrees
Any shape with 10 sides is called a decagon. A regular decagon is a shape with 10 even sides, so you are looking for an irregular decagon.
A regular decagon has rotational symmetry = 10.For irregular decagons, it could be less (either 2 or none.)
A regular decagon will have 5 pairs of parallel sides, however, irregular decagons can have no parallel sides.
It still has ten sides, same as a normal decagon. "Irregular" simply means that all the sides and angles of the decagon are not congruent.
