    Iinkcukacha zeMveliso

    Iithegi zeMveliso

    I-spiral yethuiityhubhu ezidityanisiweyozenziwe ngononophelo. Siqala ngeemicu zentsimbi okanye iipleyiti eziqengqelekayo, sizigoba size siziguqule ezi zinto zibe zizangqa. Emva koko sizidibanisa ukuze senze umbhobho oqinileyo. Ngokusebenzisa iindlela ezahlukeneyo zokuwelda ezifana nokuwelda nge-arc, siqinisekisa ukomelela nokuqina kweemveliso zethu.
