Is the decagon a regular?

Any Polygon can be a regular figure, if the figure has all straight sides and edges, with all the same length. If the decagon had all straight edges, sides, and same lengths of sides, it would be a regular figure. Otherwise, it would not, and would be an irregular Decagon.

* * * * *
