Yes rectangles and parallelograms have rotation symmetry. rectangles and parallelograms have a rotational symmetry of 2.
I hope this information helps you.
Yes it does. As long as it has a symmetry without rotation. If you do the rotation either way it does have symmetry. :)
The quadrilaterals that always have both line symmetry and rotational symmetry are squares and rectangles. Squares have four lines of symmetry and rotational symmetry of order 4, while rectangles have two lines of symmetry and rotational symmetry of order 2. Other quadrilaterals, like rhombuses and parallelograms, may have one type of symmetry but not both. Thus, squares and rectangles are the only quadrilaterals that consistently possess both symmetries.

Yes.
A diamond has two rotation symmetry. It is possible to have a diamond that does have four of rotation symmetry.
Yes it does. As long as it has a symmetry without rotation. If you do the rotation either way it does have symmetry. :)
rotation symmetry of a parallelogram Sequence
Sometimes called rotation symmetry, or symmetry of rotation. If you have an object that can be turned through a certain angle (like rotating a cube through 90o) and then it looks identical, then that object has a certain symmetry under rotation. If you can turn it through any angle, like a cylinder, then it has rotation (or rotational) symmetry.
Rectangles and Rhombuses (have at least 2 lines of symmetry).
