Characteristics of angular displacement:
i. Instantaneous angular displacement is a vector quantity (true vector), so it obeys commutative and associative laws of vector addition.
ii. Finite angular displacement is a pseudo vector.
iii. Direction of infinitesimal angular displacement is given by right hand thumb rule or right handed screw rule.
iv. For anticlockwise sense, angular displacement is taken as positive while in clockwise sense, angular displacement is taken negative.
