Guharura ingazi n'inzira 180° n'urubuga ruringaniye
Ku ngazi iyo ari yo yose, urugendo hagati y’ingazi rukwiye kuba rumwe.
Muri ivyo, ugutera hasi birashobora gufatwa nk’iyindi ntambwe.
Injira uburebure kuva ku rugero rw’igorofa ryo hasi gushika ku rugero rw’igorofa ry’igorofa rya kabiri.
Sobanura uburebure bw’aho ufungura - urugendo ingazi zawe zizofata.
Ingano zishobora gusobanurwa mu metero, milimetero na sentimetero.
Porogarama izoca iharura ubwayo uburebure n’ubwaguke bw’intambwe, imfuruka y’uguhengamira be n’ingero z’urudodo rwo hejuru n’urwo hasi.
Kugira ngo uhitemwo uburyo bwiza bwo gukoresha ingazi, hindura igitigiri c’intambwe, maze porogarama izoguha impanuro ku bijanye n’ukuntu yoba nziza.
Ubu urashobora guhitamwo gukora igishushanyo c’umwirabura n’umweru canke c’amabara.
Ubwaguke bw’igikoresho co guhinduranya ingazi bungana n’ubwaguke bw’ingazi.
