Parallelogram and Rotational Symmetry
Look at the parallelogram below. It happens to be a special parallelogram called a rhombus because all of its sides are congruent. It will rotate and show you how many places it can stop and look like a the original parallelogram/rhombus. You can tell that it is moving in a clockwise manner by finding the corner that is marked for your convenience.
The order is 2 and the magnitude of rotation is 180 degrees. Do you think that all parallelograms have rotational symmetry? If not, draw one that does not have rotational symmetry.
