R1 is typically connected to the collector of Q1, acting as a load to set the output current and voltage levels, thus it's the output resistance of Q1. R2 is often connected in the base circuit of Q2, providing the necessary biasing voltage for Q2 to operate correctly, making it the input resistance of Q2.
