Cov yam ntxwv ntawm a peb - qhov seem daim duab yog lub ntsej muag, ntug thiab vertices. Cov peb qhov ntev sau cov npoo ntawm 3D geometric puab . Lub voos xwmfab, lub kaum sab xis prism, kheej kheej, lub khob hliav qab thiab lub tog raj kheej yog qhov yooj yim 3 - cov duab puab peb pom ib ncig ntawm peb.

Tsuas yog li ntawd, dab tsi yog 3 qhov loj me txhais?

Hauv geometry, a peb - qhov loj me canbe txhais tau tias yog ib qho khoom daim duab los yog ib yam khoom los yog puab uas muaj peb qhov ntev - ntev, dav thiab qhov siab. Tsis zoo li ob- cov duab puab , peb - cov duab puab muaj thickness ordepth.

Ib tug kuj yuav nug, dab tsi yog lub npe ntawm peb seem? Muaj ob pawg ntawm peb seem duab uas koj tuaj yeem yooj yim npe . Cov no suav nrog cov prisms thiab thepyramids. Prisms muaj ob lub hauv paus sib luag thiab sab nraud uas txuas cov hauv paus yog parallelograms. Pyramids muaj ib lub hauv paus thiab sab sab yog daim duab peb sab.

Ib yam li ntawd, ib tug yuav nug, dab tsi yog qhov seem?

Ib ob- qhov loj me yog a puab uas muaj qhov ntev thiab dav tab sis tsis muaj qhov tob. Hauv lej, cov duab (cov qauv lej) yog muab los ntawm cov khoom hauv lub ntiaj teb tiag tiag uas muaj cov yam ntxwv geometric. Piv txwv ib.

Dab tsi yog daim duab peb sab?

Txhais. Peb - qhov seem mediaoccupies qhov chaw txhais los ntawm qhov ntev ntawm qhov siab, dav thiab qhov tob. Nws suav nrog cov duab puab, kev teeb tsa thiab kev ua haujlwm kos duab , kho kom zoo nkauj kos duab , thiab productdesign.
