Izici eziyisisekelo zeprism

Kulolu shicilelo, sizocubungula izici eziyinhloko ze-prism (ngokuphathelene nezisekelo, imiphetho eseceleni, ubuso nokuphakama), ezihambisana nazo nemidwebo ebonakalayo ukuze kube nombono ongcono wolwazi olwethuliwe.

Qaphela: sihlole incazelo ye-prism, izakhi zayo eziyinhloko, izinhlobonhlobo nezinketho ze-cross-section, ngakho-ke ngeke sigxile kuzo ngokuningiliziwe lapha.

Izakhiwo zePrism

Sizocubungula izakhiwo sisebenzisa isibonelo seprism eqondile ene-hexagonal, kodwa ziyasebenza kunoma yiluphi olunye uhlobo lwesibalo.

Impahla 1

Iprism inezisekelo ezimbili ezilinganayo, okungamapholygoni.

Labo. ABCDEF = A₁B₁C₁D₁E₁F₁

Impahla 2

Ubuso obusemaceleni banoma iyiphi iprism bungamapharalelogramu.

Esithombeni esingenhla ithi: AA₁B₁B, BB₁C₁C, CC₁D₁D, DD₁E₁E, EE₁F₁F и AA₁F₁F.

Impahla 3

Yonke imiphetho eseceleni yeprism iyahambisana futhi iyalingana.

• AA₁ = BB₁ = CC₁ = DD₁ = EE₁ = FF₁
• AA₁ || BB₁ || CC₁ || DD₁ || EE₁ || FF₁

Impahla 4

Ingxenye ye-perpendicular ye-prism itholakala kuma-engeli angakwesokudla kubo bonke ubuso obusemaceleni kanye nemiphetho yesibalo.

Impahla 5

Ukuphakama (h) yanoma iyiphi i-prism ethambekele ihlale ingaphansi kobude bonqenqema olusemaceleni. Futhi ukuphakama kwesibalo esiqondile silingana nomphetho wayo.

• Emkhiwaneni. kwesokunxele: h = AA₁
• Emkhiwaneni. icala: h <AA₁
