Ambidexterity is the ability to use both the right and left hand equally well. [1] [2] When referring to objects, the term indicates that the object is equally suitable for right-handed and left-handed people. When referring to humans, it indicates that a person has no marked preference for the use of the right or left hand.
The "proper right" hand of a figure is the hand that would be regarded by that figure as its right hand. [1] In a frontal representation, that appears on the left as the viewer sees it, creating the potential for ambiguity if the hand is just described as the "right hand".

Therefore, a symmetric object has sinistral and dextral directions arbitrarily defined by the position of the observer, while an asymmetric object that shows chirality may have sinistral and ...

While studies of handedness show that only 10% of the general population is left-handed, the proportion of left-handed MLB players is closer to 39% of ...
While human beings are more right-handed as animals, it is supposed that left-handedness could be latent. Experiments support Luria's proposition that a left-top preference in Arm Folding points to "latent" left-handedness, but only if associated with a right-top preference in hand clasping. [13]
