Are the angles other than the C-C-C angles in cyclopropane and cyclobutane still 109.5° as the acyclic compound, or what?




The other bond angles can't all be $109.5°$ if the angles in the ring are different from that. Bond angles around an atom are not independent variables because the amount of space to be spanned is fixed.
