Nyuma yisahani imaze gushyirwaho ku isahani, igishushanyo mbonera cya Angle no kugenda kw'ikinyabiziga ntizagira ingaruka.
Isahani y'imbere yashizwe ku bunini bw'ikinyabiziga 2. Icyapa cyashyizwe ku isahani y'imbere hagomba kuba ku ndege y'ibumoso mu ndege y'ikinyabiziga, kandi hafi y'isahani y'imbere y'umwenda w'ikinyabiziga, kandi hafi y'isahani y'imbere y'umwenda w'ikinyabiziga, kandi hafi y'isahani y'imbere mu binyabiziga, maze isahani y'imbere mu ndege y'ikinyabiziga, kandi ikipe y'imbere kandi isahani y'isahani ntishobora kurenza inkombe y'iburyo bw'Imbere ya imodoka.
Isahani yashizwe ku isahani y'imbere igomba kuba perpendicular indege itambitse, kandi isahani y'imbere ntishobora kwemererwa gusubira inyuma kuruta ibyo
15 ° Isahani yimpuhwe zizaba ziri kumpera yinyuma yimodoka. Ikipe yimpushya zashyizwe ku isahani y'inyuma igomba kuba perpendicular cyangwa hafi yindege ndende ya Symemetrie yimodoka kandi izaba kuruhande rwiburyo bwindege ndende yimodoka. Isahani yinyuma yimpapuro hamwe nicyiciro cya plate clate ntishobora kurenza inkombe yibumoso bwimbere yimodoka. Iyo uburebure bwisahani yo hejuru yisahani yinyuma hejuru yubutaka burenze 1.2m, uburebure bwuruhande rwimbere yisahani yinyuma munsi ya 30 °
15 °
