A decagon need not have any lines of symmetry. It can also have 1 or 10 lines of symmetry.
A trapezoid has no rotational symmetry.
No a Z doesn't have a rotational symmetry
It has line symmetry (straight down the center) but not rotational symmetry.
It does have rotational symmetry of order three.
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 regular decagon has rotational symmetry = 10.For irregular decagons, it could be less (either 2 or none.)
ice cream and panckakes * * * * * A decagon need not have any but the default number (1) of rotational symmetry. It can have rotational symmetry of order 2, 5 or 10.
A decagon can have rotational symmetries of order 1, 2, 5 or 10.
Any shape with an equal number of sides... Square, hexagon, octagon, decagon... etc.
A decagon need not have any lines of symmetry. It can also have 1 or 10 lines of symmetry.
A trapezium does not have rotational symmetry.
The letters H and Z have both line symmetry and rotational symmetry
It has 8lines of rotational symmetry
It has rotational symmetry to the order of 2
Equilateral triangles have rotational symmetry.
