Ua ntej, yog tias a kev hloov pauv sib tshuam ob kab yog li ntawd cov ces kaum sib raug yog congruent, ces tus kab yog parallel . Thib ob, yog tias a kev hloov pauv sib tshuam ob kab yog li ntawd sab hauv cov ces kaum ntawm tib sab ntawm lub transversal yog supplementary, ces cov kab yog parallel.
Ntxiv mus, dab tsi yog transversal ntawm parallel kab?
Parallel Kab & Kev sib hloov . A kev hloov pauv yog a kab , los yog kab ntu, uas cuam tshuam ob lossis ntau dua lwm yam kab , los yog kab ntu. Thaum a kev hloov pauv kev sib tshuam kab sib npaug , ntau lub ces kaum yog congruent.
Ib tug kuj yuav nug, dab tsi yog transversal kab thiab kaum? Hloov pauv . Lus txhais: A kab uas txiav hla ob lossis ntau dua (feem ntau yog sib npaug) kab . Hauv daim duab hauv qab no, lub kab AB is a kev hloov pauv . Nws txiav hla lub parallel kab PQ thiab RS. Yog nws hla lub parallel kab ntawm txoj cai lub kaum sab xis nws yog hu ua perpendicular kev hloov pauv.
Nyob rau hauv txoj kev no, dab tsi yog cov npe ntawm cov ces kaum ntawm cov kab sib txuas?
Hauv txhua qhov kab sib npaug nyob sib ze lub kaum sab xis yog supplementary. Cov lub kaum sab xis muaj tshwj xeeb npe txheeb xyuas lawv txoj haujlwm nrog kev hwm rau kab sib npaug thiab transversal. Lawv sib xws lub kaum sab xis , hloov sab hauv lub kaum sab xis , los yog alternate sab nrauv lub kaum sab xis . Ib lub kaum sab xis yog congruent rau nws matched lub kaum sab xis.
Puas yog cov kab sib txuas sib txuas?
Yog ob kab sib npaug yog txiav los ntawm ib tug transversal, cov ces kaum sib raug kev sib haum xeeb . Yog ob kab yog txiav los ntawm ib tug transversal thiab cov ces kaum sib raug kev sib haum xeeb , cov kab yog parallel . Sab hauv Angles ntawm Tib Sab ntawm Transversal: Lub npe yog ib qho kev piav qhia ntawm "qhov chaw" ntawm cov ces kaum no.

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 txhua qhov sib npaug sib npaug sib npaug?
Thawj qhov sib npaug sib npaug yog qhov tseeb yog tias nws muaj kev txuag kom muaj nuj nqis. Piv txwv li, qhov sib npaug sib cais yeej ib txwm muaj tseeb, txij li lub ntsiab lus lawv yog ntawm daim ntawv: M(y) + N(t) = 0, yog li ϕ(t, y) = A(y) + B(t) yog a khaws cia kom muaj nuj nqis
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
Puas yog nws ua tau rau ib qho kev sib npaug ntawm ob txoj kab sib npaug kom tsis muaj kev daws teeb meem piav qhia koj qhov laj thawj?
Cov kab ke ntawm kab sib npaug tuaj yeem tsuas muaj 0, 1, lossis ib qho kev daws teeb meem tsis kawg. Ob kab no tsis tuaj yeem hla ob zaug. Cov lus teb raug yog tias qhov system muaj ib qho kev daws teeb meem. Total Number of Points Number of 2-Point Baskets Number of 3-Point Baskets 17 4 (8 ntsiab lus) 3 (9 points) 17 1 (2 points) 5 (15 points)
Dab tsi yog qhov sib txawv ntawm cov kab lus sib npaug thiab qhov sib npaug sib npaug?
Cov kab lus sib npaug muaj qhov muaj txiaj ntsig zoo ib yam tab sis tau nthuav tawm nyob rau hauv ib hom ntawv sib txawv uas siv cov khoom ntawm cov lej xws li ax + bx = (a + b) x yog cov kab lus sib npaug. nruj me ntsis, lawv tsis yog 'sib npaug', yog li peb yuav tsum siv 3 kab sib luag hauv 'sib npaug' es tsis yog 2 raws li qhia ntawm no
