Nyob rau hauv geometry, collinearity ntawm ib pawg ntawm cov ntsiab lus yog cov cuab yeej ntawm lawv dag ntawm ib kab. Ib txheej ntawm cov ntsiab lus nrog cov cuab yeej no tau hais tias yog collinear. Feem ntau, lo lus tau siv rau cov khoom sib dhos, uas yog, yam khoom "hauv kab" lossis "hauv kab".
Ib qho piv txwv ntawm tus collinear yog dab tsi?
Peb lossis ntau lub ntsiab lus uas nyob ntawm tib kab yog cov ntsiab lus sib dhos. Piv txwv: … Tus points D, B thiab E pw ntawm kab n. Lawv yog collinear.
txhais tau tias yog dab tsi yog collinear?
Peb los yog ntau tshaj yog hais tias collinear yog tias lawv tag nrho cov lus dag ntawm tib txoj kab ncaj nraim. Yog tias A, B thiab C yog collinear ces..
Puas collinear txhais tias sib npaug?
Txoj kev daws teeb meem: Ob lub vectors raug suav tias yog collinear yog tias qhov piv ntawm lawv cov kev sib koom ua ke yog sib npaug Txij li P1/Q 1=P2/Q2=P3/Q 3, cov vectors → P thiab → Q tuaj yeem suav tias yog cov vectors collinear. Kev daws: Ob lub vectors raug suav tias yog cov vectors collinear yog tias ib lub vector yog qhov ntau ntawm cov vector.
Lub ntsiab lus ntawm collinear hauv kev sib koom ua ke geometry yog dab tsi?
Collinear cov ntsiab lus yog cov ntsiab lus uas nyob ntawm tib txoj kab ncaj nraim lossis hauv ib kab. Yog hais tias ob los yog ntau tshaj ob lub ntsiab lus nyob ntawm ib txoj kab nyob ze los yog nyob deb ntawm ib leeg, ces lawv hais tias yog collinear, nyob rau hauv Euclidean geometry.
