WebSep 22, 2024 · $\map P 1$ is true by definition of the usual ordering on real numbers: $\cmod {z_1} \le \cmod {z_1}$ Basis for the Induction $\map P 2$ is the case: $\cmod {z_1 + z_2} \le \cmod {z_1} + \cmod {z_2}$ which has been proved in Triangle Inequality for Complex Numbers. This is our basis for the induction. Induction Hypothesis
