A procedure for identifying the direction of a vector for angular motion. The angular motion vector is represented by an arrow drawn so that if the curled fingers of a person's right hand points in the direction of rotation, the direction of the arrow coincides with the direction indicated by the extended thumb. The magnitude of the vector is indicated by the length of the arrow. Any angular motion vector can be represented in this way and can be either added to a corresponding vector to obtain a resultant or can be resolved into components using a parallelogram of vectors.
