(A) Let us analyze the bond angles for each pair:$(a) BF_3$ and $BCl_3$ are both $sp^2$ hybridized with trigonal planar geometry,so both have bond angles of $120^{\circ}$.$(b) PO_4^{3-}$ and $SO_4^{2-}$ are both $sp^3$ hybridized with tetrahedral geometry,so both have bond angles of $109.5^{\circ}$.$(c) BF_3$ is trigonal planar $(120^{\circ})$,while $PF_3$ is trigonal pyramidal ($sp^3$ with one lone pair,angle $\approx 96^{\circ}$).$(d) NO_2^+$ and $N_2O$ are both linear molecules with $sp$ hybridization,so both have bond angles of $180^{\circ}$.$(e) N_3^-$ is linear $(180^{\circ})$,while $NO_2$ is bent ($sp^2$ with one odd electron,angle $\approx 134^{\circ}$).Thus,pairs $(a), (b),$ and $(d)$ have the same bond angles.
