Ikhozanso kuyimiridwa ndi nambala yachitsanzo, yomwe ndi chiwerengero cha masentimita a m'lifupi mwake, monga ∟3 #. Chitsanzo sichimawonetsa miyeso ya makulidwe osiyanasiyana amtundu wamtundu womwewo, kotero kuti m'lifupi mwake ndi makulidwe a mbali ya Angle zitsulo zimakwanira mumgwirizano ndi zolemba zina, kuti mupewe kuimiridwa ndi chitsanzo chokha. Hot adagulung'undisa ofanana-m'mphepete Zolinga zitsulo ndi 2 # -20 #. Chitsulo cha ngodya chikhoza kupangidwa ndi zigawo zosiyana zopanikizika malinga ndi zosowa zosiyanasiyana za kapangidwe kake, ndipo zingagwiritsidwenso ntchito ngati kugwirizana pakati pa zigawozo. Amagwiritsidwa ntchito kwambiri muzomangamanga zosiyanasiyana ndi zomangamanga, monga matabwa, milatho, nsanja zotumizira mphamvu, makina okweza ndi zoyendera, zombo, ng'anjo zamafakitale, nsanja zochitira, zoyika ziwiya ndi malo osungira.
