A decagon need not have any lines of symmetry. It can also have 1 or 10 lines of symmetry.

A rectangle,hexagon,octagon,triangle,decagon. It could be that looks dividable because no matter where you divide it, it has a line of symmetry... It could also be a snowflake!

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.

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

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