Za'a iya raba nau'in dangantakar dangi zuwa lokuta uku. A cikin karar farko, lokacin da "AD < bc" and a and b are adjacent bars, we can take the shortest bar (a) as the reference member and analyze its relative motion with the two adjacent bars. Since "a < b" and "c < d", we can conclude that rod a can be straightened and collinear with the two adjacent rods. In other words, a can overlap and be aligned with the neighboring rods.

Don tabbatar da wannan yanayin rashin daidaituwa, tushen rashin daidaituwa dole ne ya riƙe: "D + C> B + A". Wannan yana nuna cewa "d> c + A", wanda ya yi daidai da yanayin da aka ba.

A cikin wannan yanayin, an iyakance su duka lilo yana iyakance ga ƙasa da 180 °.

Hada da karshe daga farkon, na biyu, da na uku, da haka, zamu iya takaita hakan, a karkashin yanayin "AD < bc", regardless of the various positions, the shortest bar (a) and the second adjacent bar (b) can rotate relative to each other for a whole circle. However, the opposite pole (b or c) and the two adjacent poles of the shortest bar can only swing relative to each other, with the relative swing angle being less than 180°.

Ta hanyar bayyana mahalli motsi tsakanin su biyu hinm sarkar sarkar, za mu iya tantance irin tsarin ta hanyar zaɓar kowane sanda a matsayin firam na tunani.
