Aqqaṛ yegda taseɣleyt yebṭa ɣef 2 Pi ( ${\displaystyle r={\frac {c}{2\pi }}}$ ).

Aqqaṛ n twinest

Assaɣ gar n waqqaṛ ${\displaystyle R}$ d tseɣleyt ${\displaystyle L}$ n twinest d: ${\displaystyle R={\frac {L}{2\pi }}}$.

I usiden n waqqaṛ ${\displaystyle R}$ i twinest i yekkan ɣef 3 n wagazen ${\displaystyle A,B,C}$ nezmer ad nessemres taftart-a :

${\displaystyle R={\frac {a}{2\sin \alpha }}}$, neɣ ${\displaystyle a}$ est la longueur ${\displaystyle BC}$ et ${\displaystyle \alpha }$ akat n tɣmert ${\displaystyle {\widehat {BAC}}}$ .

Ma ttwanefken 3 n wazagen s yimsidag-nsen ${\displaystyle (x_{1},y_{1})}$, ${\displaystyle (x_{2},y_{2})}$ d ${\displaystyle (x_{3},y_{3})}$, nezmer daɣen ad nessemres taftart-a (voir asaduf n uwsi et Tajumma n ukeṛdis) :
