Ukuthuthukiswa kwe-hood yokukhipha

Iphethini yokuthuthuka ye-exhaust hood esesimweni sephiramidi encishisiwe

X - Ububanzi besisekelo esingezansi.
Y - Ukuphakama kwephiramidi.
F - Ubude besisekelo esiphezulu.
E - Ububanzi besisekelo esiphezulu.
G - Ubude bobuso obuseceleni bephiramidi. I-Apofema.
U - I-engeli yokuthambekela kwephiramidi.

Izinketho zokukhokha ku-inthanethi.

Isibali sikuvumela ukuthi ubale amapharamitha wephiramidi encishisiwe ye-tetrahedral enesisekelo esingunxande. Lokhu kuwusizo ekubaleni ama-hoods okukhipha umoya wokungenisa umoya, ihood yekhishi noma izoso, noma ihood yepayipi likashimula.

Indlela yokusebenzisa isibalo.

Khetha ubukhulu isibalo esizokwenziwa ngabo. Nikeza izilinganiso ezaziwayo nama-engeli ephiramidi. Chofoza inkinobho ethi Bala. Njengomphumela wokubala, imidwebo yephethini ye-cap ikhiqizwa.
Imidwebo ibonisa ubukhulu bezingxenye ngazinye zephethini yephiramidi encishisiwe.
Imidwebo nayo iyakhiqizwa: ukubuka kwangaphambili nokubuka okuseceleni.

Uma ubukhulu buka-E bulingana nobukhulu buka-F, khona-ke kuzoba nephiramidi enqanyuliwe evamile.
Uma ubukhulu bungu-E=0 kanye no-F=0, khona-ke kuzoba nephiramidi evamile.

Njengomphumela wokubala, ungathola:

I-engeli yokuthambekela kwephiramidi, uma ibingaziwa.
Ukusika ama-engeli ekuthuthukisweni.
Indawo ephezulu kanye nazo zonke izindawo eziseceleni.
Indawo engaphezulu yesisekelo esingezansi.
Umthamo wephiramidi.
Ubukhulu beshidi lomsebenzi.

Ukunaka. Ungakhohlwa ukwengeza izibonelelo zokugoqa ukuze uxhume izingxenye ze-hood.
