Yes it does. As long as it has a symmetry without rotation. If you do the rotation either way it does have symmetry. :)

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).
