Ubusanzwe agace k'icyuma cya pulasitiki gashobora gukorwa mu cyuma cya 45#, kakazimwa kandi gakonjeshwa kugira ngo kongere ubushobozi bwo kwangirika. Aho inkingi y'ubuyobozi ihagaze hashobora kuba imbere cyangwa inyuma, bishobora kugenwa mu buryo bworoshye bitewe n'ingano y'icyuma. Ariko, inguni n'uburebure by'inkingi y'ubuyobozi igomba kugenwa hakurikijwe intera y'icyuma gitereka; muri rusange, inguni y'inkingi y'ubuyobozi ni 20° cyangwa 25°. Kugena inguni idahinduka bishobora koroshya ikorwa ry'icyuma gitereka, kugira ngo hirindwe ko buri gihe gikenerwa. Gukora amahembe y'impande zitandukanye. Koresha itegeko rya cosine ry'imikorere ya trigonometric kugira ngo ubare uburebure bw'inkingi y'ubuyobozi itereka.

Hari ubwoko bwinshi bwo gutunganya ifumbire ku buso, ubusanzwe ni ubuso bworoshye n'ubuso bufite ibara ry'umutuku, ari na byo bitera ingaruka ku buso bigomba gukorwa hakurikijwe amahitamo y'umukiriya.
Ubushobozi ubwo aribwo bwose bwo kurangiza ubuso mu ruganda rwacu burashobora gukoreshwa.

Igikoresho gisanzwe cy’ibumba bivuze ko igikoresho gikozwe mu bikoresho bya P20, naho igikoresho kikozwe mu ikoranabuhanga rya mirror frame. Muri rusange gikoreshwa mu gutumiza ibumba mu mahanga. Akamaro k’iyi mikoreshereze ni uko iyo habayeho ikibazo kuri icyo gikoresho, gishobora gusanwa hakoreshejwe gusa gusimbuza ibice, ibyo bikaba byiza kurushaho.
