Lub converse alternate sab nrauv ces kaum theorem justifies vim li cas kab j thiab k yuav tsum yog parallel . Lub converse alternate sab nrauv ces kaum theorem hais tias yog ob kab yog txiav los ntawm ib tug transversal thiaj li alternate sab nrauv ces kaum congruent, ces tus kab yog thaum uas tig mus.
Kuj kom paub yog, cov kab twg yog qhov sib npaug ua rau koj cov lus teb?
Yog ob kab yog txiav los ntawm ib tug transversal thiab alternate sab hauv cov ces kaum yog congruent, ces cov kab yog parallel . Yog ob kab yog txiav los ntawm ib tug transversal thiab tib-sab sab hauv cov ces kaum yog supplementary, ces cov kab yog parallel.
Ib sab saum toj no, cov kab twg yuav tsum sib npaug? vim lawv nyob rau sab hauv kab L thiab K thiab nyob rau tib sab ntawm transversal M yog li ntawd kab L thiab K yuav tsum yog parallel . vim ob kab yog txiav los ntawm ib tug transversal. thiab tib sab sab hauv cov ces kaum yog supplementary ces tus kab yog thaum uas tig mus.
Ib yam li ntawd, nws tau nug, qhov theorem twg yog qhov tseeb vim li cas cov kab m thiab n yog sib npaug thaum txiav los ntawm transversal k?
lub alternate interior angles theorem
Yuav ua li cas koj pom cov kab sib luag?
Thawj yog yog tias cov ces kaum sib raug, cov ces kaum uas nyob rau tib lub ces kaum ntawm txhua qhov kev sib tshuam, sib npaug, ces cov kab yog thaum uas tig mus . Qhov thib ob yog yog cov ces kaum sab hauv, cov ces kaum uas nyob rau opposite sab ntawm transversal thiab sab hauv kab sib npaug , yog sib npaug, ces tus kab yog thaum uas tig mus.

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
Vim li cas thiaj li yuav tsum muaj qhov sib npaug ntawm tag nrho 3 los txhawb kev loj hlob zoo tshaj plaws?
Dab tsi cais ib lub qab ntug los ntawm lwm qhov? Yuav tsum muaj kev sib npaug kom cov av khaws cov dej thiab cia dej ntws tawm ntawm nws, yog tias cov av yog xuab zeb hnyav, dej yuav yooj yim ntws tawm ntawm nws los yog cov av yog av nplaum-hnyav ces dej tsis tuaj yeem nkag los ntawm nws. thiab cov cag ntoo yuav tawm tsam
Koj tuaj yeem qhia tau li cas yog tias ob qhov sib npaug sib npaug?
Peb tuaj yeem txiav txim siab los ntawm lawv qhov sib npaug seb puas yog ob kab sib npaug los ntawm kev sib piv lawv cov nqes hav. Yog hais tias cov slopes yog tib yam thiab cov y-intercepts txawv, cov kab yog parallel. Yog tias txoj kab nqes sib txawv, cov kab tsis sib npaug. Tsis zoo li cov kab sib luag, cov kab perpendicular sib tshuam
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
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
