  In a teleparallel theory of (2+1)-dimensional gravity developed in a previous
paper, we examine generators of internal Lorentz transformations and of general
affine coordinate transformations for static circularly symmetric exact
solutions of gravitational field equation. The \lq \lq spin" angular momentum,
the energy-momentum and the \lq \lq extended orbital angular momentum" are
explicitly given for each solution. Also, we give a critical comment on Deser's
claim that neither momentum nor boosts are definable for finite energy
solutions of three-dimensional Einstein gravity.
