"Yog ob kab sib tshuam , ces raws nraim ib dav hlau muaj cov kab ." "Yog ob kab sib tshuam , ces lawv sib tshuam nyob rau hauv raws nraim ib qho point." thiab peb cov ntsiab lus noncollinear txhais lub dav hlau.
Hais txog qhov no, pes tsawg lub dav hlau tuaj yeem muaj ob txoj kab sib tshuam?
ib lub dav hlau
Ib tug kuj yuav nug, vim li cas ib txoj kab tsis tuaj yeem cuam tshuam lub dav hlau hauv ob lub ntsiab lus? Yog koj xaiv ob ntsiab lus ntawm a dav hlau thiab txuas lawv nrog ncaj kab tom qab ntawd txhua taw tes ntawm kab yuav ua on dav hlau . Muab ob ntsiab lus tsuas muaj ib tug xwb kab hla cov cov ntsiab lus . Yog li yog tias ob ntsiab lus ntawm a kab hla ib lub dav hlau ces tag nrho cov ntsiab lus ntawm kab yog on dav hlau.
Ib sab ntawm no, dab tsi yog ob txoj kab sib tshuam?
Kev sib tshuam kab A khub ntawm kab , kab ntu los yog rays yog kev sib tshuam yog hais tias lawv muaj ib qho ntsiab lus. Cov ntsiab lus no yog lawv lub ntsiab lus kev sib tshuam . Piv txwv li, ob sab nyob ib sab ntawm ib daim ntawv, ib tug kav, ib lub qhov rooj, qhov rais thiab cov ntawv.
Qhov kev sib tshuam ntawm ob lub dav hlau yog dab tsi?
Cov kev sib tshuam ntawm ob lub dav hlau hu ua kab. Dav hlau yog ob -dimensional tiaj tus.

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
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 ob khub ntawm qhov sib txawv ntawm qhov sib npaug hauv lub rhombus?
Lub rhombus muaj tag nrho cov khoom ntawm ib qho parallelogram: Ob khub ntawm sab nraud yog sib npaug. Ob leeg ntawm opposite sab yog sib npaug ntawm qhov ntev. Ob khub ntawm lub kaum sab xis sib npaug
Nws puas yuav ua rau pom qhov sib npaug ntawm kab sib npaug mus rau ib kab thiab los ntawm ib qho taw tes ntawm kab?
Qhov sib npaug ntawm ib kab uas yog parallel lossis perpendicular rau ib kab? Cov lus teb tau: Cov nqes hav ntawm cov kab sib npaug sib npaug. Hloov txoj kab nqes paub thiab cov kev sib koom ua ke ntawm ib qho taw tes ntawm lwm txoj kab rau hauv daim ntawv point-slope kom pom qhov sib npaug ntawm kab sib npaug
Ob lub dav hlau sib txawv tuaj yeem cuam tshuam ntawm ib qho chaw?
Ob lub ntsiab lus sib txawv txiav txim siab raws nraim ib kab. Nws yog cov cuab yeej no uas ua rau lub dav hlau 'flat.' Ob kab sib txawv nyob rau hauv feem ntau ntawm ib qho chaw; ob lub dav hlau sib txawv hauv feem ntau ntawm ib kab. Yog hais tias ob txoj kab coplanar tsis sib tshuam, lawv yog parallel
