Final answer:
It is not possible to hold two hands in a fashion that exhibits rotational symmetry (besides a 360-degree one) due to anatomical differences.
Step-by-step explanation:
In physics, rotational symmetry refers to the property of an object or system to maintain its shape after it has been rotated around a certain axis. When it comes to holding two hands in a fashion that exhibits rotational symmetry (besides a 360-degree one), it is not possible due to the anatomical differences between the left and right hand. The asymmetric structure, such as the thumb placement, makes it impossible to achieve rotational symmetry for two hands.
