Thawj qhov kev daws teeb meem: kom dhos ib lub tetrahedron los ntawm kev sib tw, hauv lwm lo lus, duab peb ceg kaum. Nws yog cov duab nrog peb tog ntawm nws tus kheej. Yog li, peb qhov yuam kev siv tau. Qhov peb peb qhov kev sib tw yog txhua qhov kev teeb tsa nrog ib kawg ntawm lub ces kaum ntawm daim duab peb sab, thiab qhov kawg thib ob ntawm cov kev sib tw tau sib hloov ntawm apex ntawm tetrahedron. Nws hloov tawm lub pyramid nrog lub voos lub voos. Nov yog peb qho kev daws teeb meem, qhov uas tag nrho cov duab peb ceg twg yog tib yam, sib npaug, txhua sab ntawm daim duab peb sab yog sib npaug rau ib qho kev sib tw

Qhov thib ob tov: muaj pes tsawg leeg ntawm dav hlau. Ntawm no koj tuaj yeem ua yam tsis muaj kev ua kom yuam kev thiab kev sib tshuam ntawm cov ntais ntawv. Daim duab peb sab yog tsim los ntawm peb qhov yuam kev. Tom qab ntawd lwm peb qhov yuam kev raug muab, ntawm uas ib daim duab peb sab kuj raug tsim. Ib daim duab peb sab yog nyob nrog lub hauv paus nqes, thiab lwm qhov, ntawm qhov tsis sib thooj, nrog lub hauv paus sawv. Tom qab ntawd ob lub voos xwm fab sib tshooj sib tshooj. Qhov tshwm sim yog rhombus, txhua sab ntawm cov uas muaj ib daim duab peb sab uas nyob ib sab. Txhua daim duab peb sab los ntawm cov ntais ntawv tau muab kwv yees muaj qhov zoo ib yam. Sab ntawm ob tog voos plaub yog ib nrab ntawm qhov ntev ntawm kev sib tw.
