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.
Kev sib raug zoo, lub theorem twg yog qhov tseeb vim li cas cov kab m thiab n yog sib npaug?
Cia m thiab n yog ob kab thiab cov kab raug txiav los ntawm transversal k. Tom qab ntawd, yog tias peb pom tias qhov sib txawv sab hauv cov ces kaum sib npaug, ces m thiab n ua thaum uas tig mus rau ib leeg. Yog li ntawd, lub converse ntawm alternate interiors theorem kom raug justifies tias cov kab yog thaum uas tig mus thaum txiav los ntawm transversal.
Tsis tas li ntawd, qhov twg yuav tsum sib npaug 92 los ua pov thawj tias RS? Angles w and z yuav tsum sib npaug 92 ° rau ua pov thawj tas r s. Qhov no yog vim lub kaum sab xis w sib raug rau lub kaum sab xis muab, thaum lub kaum z yog vertically opposite lub kaum sab xis muab.
Ib yam li ntawd, koj ua pov thawj cov kab sib npaug li cas?
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 parallel . Qhov thib ob yog yog tias cov ces kaum sab hauv, cov ces kaum uas nyob rau sab nraud ntawm lub transversal thiab sab hauv. kab sib npaug , yog sib npaug, ces tus kab yog parallel.
Cov kab twg yog qhov sib npaug ua rau koj cov lus teb kab P thiab Q?
kab p i q yog thaum uas tig mus vim tib sab sab hauv cov ces kaum yog congruent. kab p i q yog thaum uas tig mus vim qhov sib txawv sab nrauv sab nrauv yog congruent Kab l i m yog thaum uas tig mus vim tib sab sab hauv cov ces kaum yog supplementary Kab l i m yog thaum uas tig mus vim lwm cov ces kaum sab hauv yog supplementary.

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
