Bond angle remains constant,dihedral angle changes.

(A) In ethane $(CH_3-CH_3)$,the bond angles (e.g.,$H-C-H$ and $C-C-H$) remain constant because the hybridization of carbon atoms $(sp^3)$ does not change during rotation.However,the dihedral angle (the angle between the planes of $H-C-C$ bonds on adjacent carbons) changes continuously from $0^{\circ}$ to $360^{\circ}$ as the molecule undergoes rotation around the $C-C$ sigma bond.
