Did you mean decagon? You misspelled the word. A decagon is a shape with 10 sides
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.
Ten. The prefix "deca-" means ten.
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.
