RESUMO

We investigate some properties of scattering amplitudes in gauge theories, in tree approximation. A brief introduction about classical aspects and the Dam-Veltman discontinuity are discussed. We treat specifically the gluon-gluon and graviton-graviton scattering amplitudes and its properties of gauge invariance. To obtain the Feynman rules and amplitude calculation, we make some algorithms in computer algebra
