A decagon can have rotational symmetries of order 1, 2, 5 or 10.
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.

A decagon need not have any lines of symmetry. It can also have 1 or 10 lines of symmetry.
A decagon need not have any lines of symmetry. It can have 10.
10 axes of symmetry
10 lines 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.
10
A regular decagon has rotational symmetry = 10.For irregular decagons, it could be less (either 2 or none.)
decagon
A regular decagon has 10 lines of symmetry. Each line of symmetry can be drawn through a vertex and the midpoint of the opposite side, as well as through the midpoints of two opposite sides. This symmetry reflects the decagon's equal angles and sides, allowing for multiple symmetrical divisions.
A diamond has two rotation symmetry. It is possible to have a diamond that does have four of rotation symmetry.
