Lintho tsa motheo tsa prism

Khatisong ena, re tla nahana ka matlotlo a mantlha a prism (mabapi le metheo, mahlakoreng a mahlakoreng, lifahleho le bophahamo), re tsamaisana le litšoantšo tse bonoang bakeng sa pono e ntle ea tlhaiso-leseling e fanoeng.

Hlokomela: re hlahlobile tlhaloso ea prism, likarolo tsa eona tsa mantlha, mefuta le likhetho tsa likarolo tse fapaneng, ka hona re ke ke ra lula ho tsona ka botlalo mona.

Thepa ea Prism

Re tla nahana ka thepa ho sebelisa mohlala oa prism e otlolohileng ea hexagonal, empa e sebetsa ho mofuta ofe kapa ofe oa setšoantšo.

Thepa 1

Prism e na le metheo e 'meli e lekanang, e leng polygone.

Tseo. ABCDEF = A₁B₁C₁D₁E₁F₁

Thepa 2

Lifahleho tse lehlakoreng tsa prism efe kapa efe ke parallelograms.

Setšoantšong se ka holimo ke: AA₁B₁B, BB₁C₁C, CC₁D₁D, DD₁E₁E, EE₁F₁F и AA₁F₁F.

Thepa 3

Mathoko ohle a mahlakoreng a prism a a bapisa mme a lekana.

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

Thepa 4

Karolo ea perpendicular ea prism e fumaneha ka mahlakoreng a nepahetseng ho lifahleho tsohle tsa mahlakoreng le mahlakoreng a setšoantšo.

Thepa 5

Height (h) prism efe kapa efe e sekametseng e lula e le tlase ho bolelele ba moeli oa eona o ka morao. 'Me bophahamo ba setšoantšo se otlolohileng bo lekana le bohale ba eona.

• Ka feiga. ka ho le letšehali: h = AA₁
• Ka feiga. nyeoe: h <AA₁
