1.4.1. Symmetrical signs
In a symmetrical sign both hands have the same handshape and the movements of the two hands can be either the exact mirror image of each other along a body plane (e.g. party), or the initial and final settings of the movements might alternate between the two hands at a given time (e.g. tree). The plane of symmetry can be saggital as in party and tree, transverse as in turtle, or coronal as in cınema.

Rarely, the hands have different handshapes, yet move symmetrically (e.g. bus_stop, shısh_kebab). In this rare group, the hands are generally in contact or are very close to each other.
