${\mathrm{CH}}_3^{+}$shows ${\mathrm{sp}}^2$ hybridisation whereas ${\mathrm{CH}}_3^{-}$shows ${\mathrm{sp}}^3$ hybridisation.

${\mathrm{NH}}_4^{+}$has a regular tetrahedral geometry.

${\mathrm{sp}}^2$-hybridised orbitals have equal s and p character.

Hybridised orbitals generally form $\sigma$-bonds.
