Achishandisa nzira iyi, aigona kupa mhinduro dzemibvunzo kusvika padanho rakaringana rekururama, uku achijekesa miganhu yemhinduro yacho. Nzira iyi inozivikanwa senzira yekupera, uye akaishandisa kufungidzira kukosha kwe π. Mukuyera kweDenderedzwa akazviita nekudhirowa hexagon yakakura kunze kwedenderedzwa uye hexagon diki mukati medenderedzwa, uye zvishoma nezvishoma akapeta kaviri huwandu hwemativi e polygon yega yega, achiverenga kureba kwemativi epolygon yega yega padanho rega rega. Sezvo huwandu hwemativi hunowedzera, zvinowedzera kusvika padanho chairo renhamba ina. Mushure mekuratidzira nekupokana (reductio ad absurdum), apo mativi ese aive akaenzana, aigona kupa mhinduro kumatambudziko kusvika padanho rekusarudzika, achitaura miganho mukati memhinduro.
