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 general parallelogram has rotational symmetry of order two.
It has 8 rotational symmetry.
0,one full turn doesn't count as a rotational symmetry
Yes. A circle has infinitely many lines of symmetry and it also has rotational symmetry of infinite order.
None.
i am not sure but i think a trapezium has 1 order of rotational symmetry
All of them. To be precise, since a circle is perfectly round (in theory, although humans can't reproduce such circularity - is that a word?) it will have infinity rotational symmetry.
I believe that an octagon has 16 lines of symmetry.
The order of rotational symmetry for a circle is infinite. This is because it can be rotated any amount from the middle and it will still look the same. You can use a special sign to show this: ∞

There are no right angles in an octagon.An 8 sided octagon normally has no right angles.
A parallelogram has a rotational symmetry of 2!
triangles have 0 rotational symmetry
it has 5 rotational symmetry
A line has rotational symmetry of order 2.
