A nonrectangular parallelogram has rotational symmetry, but not line symmetry. Additionally, shapes such as the letters S, N, and Z can be rotated to show rotational symmetry, although they do not have line symmetry.
The rectangle's rotational symmetry is of order 2. A square's rotational symmetry is of order 4; the triangle has a symmetry of order 3. Rotational symmetry is the number of times a figure can be rotated and still look the same as the original figure.
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: ∞

No. Objects can have reflective symmetry but no rotational symmetry.
Yes. An object with rotational symmetry is one that looks the same after a certain amount of rotation.
False
Reflectional symmetry
Its order of rotational symmetry.
Rotational symmetry is the amount of symmetry you would have if you rotated the shape.
This is the definition of "rotational symmetry", or if the statement is true for any number of degrees of rotation it is also "circular symmetry.".
It only has rotional symmetry if it can be rotated around a point less than 360 degrees and staying the same shape like if you rotate a square 90 degrees it will be the same shape as in the beginning.. Kind of confusing
The modern answer is that if the shape only fits once onto the original when rotated 360o it has no rotational symmetry. A right triangle only fits once when rotated 360o so it has no rotational symmetry.
