M'bukuli, tiwona tanthauzo, zinthu, mitundu ndi zinthu zazikulu za parallelepiped, incl. amakona anayi. Zomwe zaperekedwa zimatsagana ndi zojambula zowoneka bwino kuti mumvetsetse bwino.
Tanthauzo la bokosi
Parallelpiped ndi chithunzi cha geometric mumlengalenga; hexagon yomwe nkhope zake zimakhala zofananira. Chithunzicho chili ndi m'mphepete 12 ndi nkhope 6.
Parallelepiped ndi mitundu yosiyanasiyana yokhala ndi parallelograph ngati maziko. Mfundo zazikuluzikulu za chiwerengerocho ndi zofanana ndi za prism.
Zindikirani: Mafomu owerengera (azithunzi zamakona anayi) ndi parallelepiped amaperekedwa m'mabuku osiyana.
Mitundu ya parallelepipeds
- Parallelepiped molunjika - nkhope zam'mbali za chithunzicho ndizokhazikika ku maziko ake ndipo ndi rectangles.
- Parallelepiped yolondola ikhoza kukhala amakona atatu Maziko ake ndi amakona anayi.
- Oblique parallelepiped - nkhope za m'mbali sizikhala zogwirizana ndi maziko.
- - mbali zonse za chithunzicho ndi mabwalo ofanana.
- Ngati nkhope zonse za parallelepiped zili zofanana, zimatchedwa alireza.
Bokosi katundu
1. Nkhope zotsutsana za mapalelo amafanana ndipo ndi ofanana ma paralelogalamu.
2. Ma diagonal onse a parallelepiped amadutsana panthawi imodzi ndipo amagawidwa pakati pa izo.
3. Mzere wa diagonal (D) a rectangular parallelepiped ndi ofanana ndi kuchuluka kwa mabwalo a miyeso yake itatu: kutalika (a), m'lifupi (B) ndi utali (C).
d2 =A2 + b2 +c2
Zindikirani: kwa parallelepiped, gwiritsaninso ntchito.
