Lub ntsiab lus yog qhov tseeb a xoom-dimensional geometricobject . Yog vim li cas tom qab xaiv cov lus teb no yog qhov point tsis muaj qhov ntev, dav lossis qhov siab.

Hais txog qhov no, dab tsi yog qhov zero dimensional geometric khoom?

Zero Dimensions : Ib point muaj zerodimensions . Tsis muaj qhov ntev, qhov siab, dav, lossis ntim. Itsonly khoom yog nws qhov chaw. Koj tuaj yeem muaj qhov sau los ntawm cov ntsiab lus, xws li cov ntsiab lus kawg ntawm kab lossis cov ces kaum ntawm square, tab sis nws tseem yuav yog xoom - dimensionalobject.

Ib yam li ntawd, dab tsi yog ib qhov ntev thiab muaj qhov ntev tsis kawg? Yog li ntawd, ntev ntawm dav hlau yog tsis kawg tab sis nws tsis yog ib - qhov seem . Ray: Nws yog ib feem ntawm kab uas nws tus kheej ib point yog tsau thiab tuaj yeem txuas ntxiv los ntawm lwm qhov chaw mus rau ib qho ntev tsis kawg . Yog li ntawd, Ray muaj infinitelength . Point: Nws tuaj yeem txhais tau tias yog qhov chaw uas tsis yog muaj ntev , dav thiab qhov siab.

Kuj paub, pes tsawg qhov ntev yog nyob ntawm ib kab?

Cov txheej txheem ntawm kab nyob rau hauv ib lub dav hlau istwo- qhov seem raws li piav ib yam ib tug ntawm lawvuniquely yuav tsum tau ob tsis: txoj kab nqes thiab y-intercept (m, b) los yog x thiab y-intercepts (x₀, tus y₀), piv txwv.

Cov ntsiab lus ntawm tib kab hu ua dab tsi?

Collinear Cov ntsiab lus : cov ntsiab lus uas dag rau ntawm tib kab . Coplanar Cov ntsiab lus : cov ntsiab lus tias dag inthe ib yam dav hlau. Sab Nrauv Rays: 2 rays uas nyob ntawm tib kab , nrog ib qho kawg kawg thiab tsis muaj lwm yam cov ntsiab lus zoo sib xws.
