Khatisong ena, re tla shebana le tlhaloso, likarolo, mefuta le thepa ea mantlha ea parallelepiped, ho kenyeletsoa. khutlonnetsepa. Lintlha tse hlahisitsoeng li tsamaea le litšoantšo tse bonoang bakeng sa temoho e ntle.
Tlhaloso ea lebokose
Parallelpiped ke setšoantšo sa geometri sebakeng; hexagon eo lifahleho tsa yona dileng tsa papiso. Setšoantšo sena se na le mahlakore a 12 le lifahleho tse 6.
Parallelepiped ke mefuta e fapaneng e nang le parallelogram joalo ka metheo. Lintlha tse ka sehloohong tsa setšoantšo li tšoana le tsa prism.
Hlokomela: Liforomo tsa ho bala (bakeng sa setšoantšo sa kgutlonne) le parallelepiped li hlahisoa ka lingoliloeng tse fapaneng.
Mefuta ea parallelepipeds
- E otlolohileng parallelepiped - lifahleho tse lehlakoreng tsa setšoantšo li na le li-perpendicular ho metheo ea eona 'me li na le li-rectangles.
- Parallelepiped e nepahetseng e ka ba sekhutlo Metheo ke likhutlonnetsepa.
- Oblique parallelepiped - lifahleho tse lehlakoreng ha li perpendicular ho metheo.
- – mahlakore ohle a setšoantšo a na le lisekoere tse lekanang.
- Haeba lifahleho tsohle tsa parallelepiped li tšoana le li-rhombuse, e bitsoa rhombohedron.
