A regular decagon has rotational symmetry = 10.For irregular decagons, it could be less (either 2 or none.)

A dodecagon need not have any lines of symmetry. It can have a maximum of 12.
A decagon has 10 sides, so it also has 10 angles. Each angle of a decagon is 36 degrees (360 degrees divided by 10). Therefore, a decagon has 10 angles of rotation symmetry.
10 axes of symmetry
heck yeah it does * * * * * It can do, but it need not have any non-trivial rotational symmetry. A regular decagon will have rotational symmetry of order 10.
