Tiag tiag kab sib npaug ua tsis tau ntsib ntawm ib qho taw tes lossis kev sib tshuam vim lawv tau txhais tias txoj kev, yog tias ob kab yuav sib tshuam ces lawv yuav tsis nyob kab sib npaug.
Raws li txoj cai, vim li cas cov kab sib txuas tsis sib tshuam?
Kev txhais ntawm Parallel kab hais tias Ob kab uas dag nyob rau hauv tib lub dav hlau uas tsis txhob sib tshuam hu ua kab sib npaug . Hauv lwm lo lus parallel kab tsis sib tshuam ib leeg los ntawm txhais. Yog txoj kab nqes ntawm ob kab yog sib npaug, piv txwv li qhov hloov pauv hauv y ntawm tus nqi hloov pauv hauv x yog sib npaug lawv yuav yeej tsis sib tshuam.
Ib yam li ntawd, puas yog ob kab uas tsis tau ntsib yuav tsum ua tib yam? Ob kab nyob rau tib qhov chaw peb-dimensional uas ua tsis yog kev sib tshuam xav tau tsis yog thaum uas tig mus . Tsuas yog lawv yog nyob rau hauv ib tug dav dav yog lawv hu thaum uas tig mus ; txwv tsis pub lawv yog npe skw kab.
Ua raws li qhov no saib, puas cov kab sib txuas thaum kawg ntsib?
Hauv qhov projective geometry, ib khub ntawm kab ib txwm sib tshuam ntawm qee qhov taw tes, tab sis parallel kab ua tsis sib tshuam hauv lub dav hlau tiag. Cov kab ntawm infinity yog ntxiv rau lub dav hlau tiag. Qhov no ua tiav lub dav hlau, vim tam sim no kab sib npaug sib tshuam ntawm ib qho chaw uas nyob rau ntawm kab ntawm infinity.
Puas yog cov kab sib txuas sib tshuam ntawm ib tus kheej?
Parallel kab ua tsis muaj nyob hauv kheej kheej geometry. Tej yam ncaj kab los ntawm qhov point P ntawm a kheej kheej yog los ntawm txhais lub voj voog loj. Ob lub voj voog loj yuav sib tshuam ntawm ob lub ntsiab lus ntawm Euclidean ntu, uas yog txoj kab uas hla kheej kheej . Tsis muaj kab sib npaug hauv kheej kheej geometry.

Yuav daws qhov tsis sib npaug ntawm cov kab sib npaug thiab cov kab sib npaug sib npaug li cas?
Kev daws qhov tsis sib npaug ntawm qhov sib npaug yog zoo ib yam li kev daws cov kab sib npaug. Qhov sib txawv tseem ceeb yog koj tig lub cim tsis sib xws thaum faib lossis muab faib los ntawm tus lej tsis zoo. Graphing linear inequalities muaj ob peb qhov sib txawv ntxiv. Qhov uas yog qhov ntxoov ntxoo muaj xws li qhov tseem ceeb uas qhov kev tsis sib xws ntawm cov kab tawm muaj tseeb
Puas yog cov kab sib txuas tsis tau ntsib?
Parallel kab tsis sib ntsib ntawm ib qho chaw. Ntu no ntawm Wikipedia muaj nqis heev ntawm no: Hauv geometry, parallellines yog kab hauv lub dav hlau uas tsis sib ntsib; uas yog, ob kab hauv lub dav hlau uas tsis cuam tshuam sib cuam tshuam ntawm ib qho twg yog hais kom sib npaug
Dab tsi yog qhov sib txawv ntawm qhov sib txawv ntawm cov kab sib txuas thiab ntau qhov sib piv?
6. (2 lub cim) Qhov sib txawv ntawm cov kab sib txuas (kev sib piv) thiab ntau qhov sib piv yog dab tsi? Cov kab sib xyaw ua ke yog npaj sib piv; uas yog, tshwj xeeb txhais tau tias yog ua ke nyob rau hauv ntau txoj kev thiab contrasted nrog rau lwm yam kev sib txuas ntawm txhais tau tias
Puas yog cov kab sib txuas ua pov thawj cov kab sib txuas?
Thawj yog yog tias cov ces kaum sib thooj, cov ces kaum uas nyob rau tib lub ces kaum ntawm txhua qhov kev sib tshuam, yog sib npaug, ces cov kab sib npaug. Qhov thib ob yog yog tias qhov sib txawv sab hauv lub kaum sab xis, cov ces kaum uas nyob rau sab nraud ntawm lub transversal thiab sab hauv cov kab sib npaug, sib npaug, ces cov kab sib npaug
Puas yog cov kab sib txuas sib txuas hauv hyperbolic geometry?
Hauv hyperbolic geometry, muaj ob hom kab sib npaug. Yog hais tias ob kab tsis sib tshuam nrog tus qauv ntawm hyperbolic geometry tab sis lawv sib tshuam ntawm nws tus ciam teb, ces cov kab yog hu ua asymptotically parallel lossis hyperparallel
