Geomatric Daim Duab Teeb
| E51.0108-AGeomatric Daim Duab Teeb | |
| Set ntawm 10 pcs, hauv 3 xim, hyim 3 ″.Nws yog siv rau cov tub ntxhais kawm theem pib kom nkag siab cov duab sib txawv geomatric. Xws li lub voos xwmfab, duab plaub, Cone, kheej kheej, Cylender, Rectangular pyramid, Daim duab peb sab prism, Pentagon prism, Hexagon prism, ua los ntawm cov yas. |
Cov khoom hauv geometry raug muab los suav ntsiab lus raws li kev tshawb nrhiav qeb ntawm peb-seem seem qhov chaw tsom xam qhov chaw. Yog li, kev kawm txog cov duab ntawm cov duab hauv cov plaub fab ntawm cov plaub fab (xws li kheej, ellipsoid, lub khob hliav qab, hyperboloid, thiab eeb) yog vim txoj kev kawm ntawm qhov tsis txawv ntawm plaub hom duab plaub hauv algebra Cov teeb meem sib txawv
Feem ntau hais lus, geometries hais los saum toj yog tshawb xyuas txhua qhov ntawm cov qauv ntawm cov qauv ntawm Euclidean qhov chaw, uas yog, cov chaw tiaj tus qauv, tsis muaj kev saib xyuas tiag rau cov qauv geometric ntawm qhov chaw nkhaus. Euclid lub axioms ntawm geometry qhov tseem ceeb piav qhia txog cov yam ntxwv geometric ntawm cov chaw tiaj. Tshwj xeeb tshaj yog lub axiom thib tsib tau ua rau tib neeg tsis ntseeg siab txog nws txoj kev raug. Vim li ntawd, tib neeg tau pib mob siab txog qhov kev ntsuas ntawm nws qhov chaw nkhaus, uas yog, "tsis yog Euclidean geometry". Non-Euclidean geometry suav nrog cov ntsiab lus feem ntau ntawm cov ntsiab lus geometric, xws li "geherry geometry", "Roche's geometry" thiab lwm yam. Ntawm qhov tod tes, thiaj li yuav coj cov ntsiab lus illusory ntawm infinity rau hauv kev soj ntsuam thaj tsam, tib neeg pib xav txog qhov ntsuas qhov ntsuas.
Feem ntau, cov duab pib thaum tsis yog Euclidean tau kawm txog cov yam ntxwv ntawm cov ntsuas tsis yog, uas yog, lawv tsis tshua muaj qhov ua nrog metric, tab sis tsuas yog tsom rau qhov chaw ntawm cov khoom ntsuas-xws li parallelism, kev sib tshuam, thiab lwm yam. Cov chaw nyob hauv cheeb tsam tau kawm los ntawm cov geometries no txhua qhov chaw nkhaus.
