Tsuas tsib lub polyhedrons ib txwm muaj: lub tetrahedron (plaub daim duab peb sab), lub voos xwmfab (rau lub ntsej muag square), lub octahedron (yim daim duab peb sab-xav txog ob lub pyramids tso rau hauv qab rau hauv qab), dodecahedron (12 lub ntsej muag pentagonal), thiab icosahedron (20 daim duab peb sab).
Muaj pes tsawg hom polyhedrons?
Polyhedra feem ntau muab faib ua ob hom- tsis tu ncua polyhedron thiab tsis xwm yeem polyhedron. Ib qho polyhedron tsis tu ncua kuj tseem hu ua platonic khoom uas nws lub ntsej muag yog cov polygons tsis tu ncua thiab muaj kev sib koom ua ke. Nyob rau hauv ib txwm polyhedron, tag nrho cov kaum sab xis ntawm polyhedral yog sib npaug. Muaj tsib lub polyhedrons tsis tu ncua.
Vim li cas tsuas muaj 5 hom polyhedrons?
Nyob rau hauv lub ntsiab lus: nws tsis tuaj yeem muaj ntau dua 5 platonic cov khoom, vim tias muaj lwm yam ua txhaum cai yooj yim txog cov npoo, kaum thiab ntsej muag peb tuaj yeem ua ke..
Dab tsi yog polyhedron thiab tsis yog polyhedron?
A polyhedron yog ib daim duab 3-dimensional uas yog tsim los ntawm polygons uas nyob ib puag ncig thaj tsam hauv qhov chaw. Non-polyhedrons yog cones, spheres, thiab cylinders vim lawv muaj ob sab uas tsis yog polygons … Lub prism yog ib tug polyhedron nrog ob congruent bases, nyob rau hauv parallel planes, thiab lateral sab yog duab plaub.
Hedron zoo li cas?
Ib daim duab peb sab uas nws lub ntsej muag yog polygons hu ua polyhedron. Lo lus no los ntawm Greek lo lus poly, uas txhais tau tias "ntau," thiab hedron, uas txhais tau tias "lub ntsej muag." Yog li, qhov tseeb tiag, ib lub polyhedron yog peb-dimensional khoom nrog ntau lub ntsej muag
