it has two folds.
None. For a 3-dimensional object, a line of symmetry implies rotational symmetry and an aircraft has no line of rotational symmetry.
4
triangles have 0 rotational symmetry
it has 5 rotational symmetry
An arrowhead shape has one line of rotational symmetry. This line runs vertically down the center, allowing the shape to be rotated 180 degrees to look the same. It does not have any other lines of symmetry.
A line has 180 degrees rotational symmetry.
A line has rotational symmetry of order 2.
None. For a 3-dimensional object, a line of symmetry implies rotational symmetry and an aircraft has no line of rotational symmetry.
Many figures. For example, an ellipse.

triangles have 0 rotational symmetry
A parallelogram has a rotational symmetry of 2!
it has 5 rotational symmetry
Rotational symmetry of order 1.
It has 1 order of rotational symmetry.
if all of the side are equal to each other, then it will have rotational symmetry. this means that if you stick a line through it and goes through the center, then it is a line of symmetry. the answer is infinity.
They have not got any rotational symmetry
