We deal with three well-known inequalities in normed spaces concerning the triangle inequality. The first is about $(p,q)$-angular distance which is a generalization of the notion of angular distance and $p$-angular distance discussed in the literature. The second relates to the Cauchy-Schowarz inequality. Finally, we introduce a norm in an inner product space through a given linear operator $T$ and then we state a refinement of triangle inequality via the original norm of the space.
