Abstract Lie point symmetries of the (2+1) sine-Gordon (S-G) equation are shown to be infinite. Through resultant similarity transformations, reduction of the equation is presented. The finite cases of symmetries are employed to obtain one-dimensional optimal system of subalgebras. Finally, Noether symmetries are utilized to determine conserved vectors for both finite and infinite cases.
