Njira yotumizira imatengerangodya zitsulo nsanja, ndipo gawo lalikulu limatenga ngodyansanja yachitsulo yachitsulo, yomwe ndi njira yothandizira ya mzere wodutsa pamtunda ndipo imathandizira woyendetsa ndi waya pansi. Zimatsimikizira kuti woyendetsa amakwaniritsa zofunikira zamtunda kuchokera pansi ndi zinthu, ndipo amatha kupirira katundu wa conductor, waya pansi ndi nsanja yokha, komanso katundu wakunja.Ngongole zitsulo, yomwe imadziwika kuti ngodya chitsulo, ndi chingwe chachitali chachitsulo chokhala ndi mbali ziwiri zopanga ngodya zakumanja. Pali equilateral ngodya zitsulo ndi wosafanana ngodya zitsulo.Equilateral angles ali ndi m'lifupi mofanana mbali zonse. Mafotokozedwe ake amawonetsedwa mu miyeso ya mm m'lifupi × m'lifupi × makulidwe. Mwachitsanzo, "∟30 × 30 × 3" amatanthauza equilateral ngodya zitsulo ndi m'lifupi 30 mm ndi makulidwe 3 mm. Itha kuwonetsedwanso ndi chitsanzo, ndiko kuti, m'lifupi, masentimita, monga ∟3 #. Nambala yachitsanzo siimayimira miyeso ya makulidwe osiyanasiyana mkati mwachitsanzo chomwecho, kotero kuti makulidwe ndi makulidwe a zitsulo za ngodya ziyenera kudzazidwa pamapangano ndi zolemba zina kuti musagwiritse ntchito nambala yachitsanzo yokha. Mafotokozedwe a zitsulo zotentha zozungulira equilateral ngodya ndi 2 # -20 #. Ngongole zitsulo zimatha kusonkhanitsidwa m'magulu osiyanasiyana olimbana ndi nkhawa malinga ndi zosowa zosiyanasiyana zamapangidwe, ndipo zitha kugwiritsidwanso ntchito ngati cholumikizira pakati pa zigawo.

Chidziwitso choyambirira ndi zofunikira zaukadaulo zakufala mzere ngodya zitsulo nsanjazojambula zimaphatikizapo zinthu zambiri monga kusankha zinthu, kukula kwa chigawocho, mapangidwe ogwirizanitsa, zofunikira zomanga, ndi kukonzekera kujambula. Zomwe zili muzojambulazo zimakhala ndi zojambula zodziwika bwino komanso zojambulajambula. Chojambula chojambula chiyenera kugawidwa m'magawo monga mabakiti, mikono yodutsa, matupi a nsanja, ndi miyendo ya nsanja. Muzojambula zamapangidwe, kupatula magawo okhazikika mongamabawuti, flanges, clamping mbale, zikhomo phazi ndi washers, mbali zonse ziyenera kuwerengedwa.
