A kite has only one line of rotational symmetry, as it is only the same if it is tilted once. (back to its normal position).
Infinitely many.
a heart have no rotational symmetry!
A regular hexagon has 6 rotational symmetries (rotational symmetry of order six) and 6 reflective symmetries (six lines of symmetry).
Rotational symmetry of order 1.
A line has 180 degrees rotational symmetry.
It has 8 rotational symmetry.
Infinitely many.
