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.
Kuj paub, dab tsi theorem proves tias ob kab yog parallel?
Yog ob kab yog txiav los ntawm ib tug transversal thiab cov ces kaum sab nrauv yog sib npaug, ces tus ob kab yog parallel . Lub kaum sab xis tuaj yeem sib npaug lossis sib npaug; koj tuaj yeem hloov lo lus "sib npaug" hauv ob qho tib si theorems nrog "kev sib haum xeeb" yam tsis muaj kev cuam tshuam cov theorem . Yog li yog tias ∠B thiab ∠L yog sib npaug (lossis congruent), lub kab yog parallel.
Ib yam li ntawd, koj puas tuaj yeem ua pov thawj tias kab P thiab Q yog sib npaug? Yog tias muaj, qhia cov postulate lossis theorem koj yuav siv. Yog tias kab yog txiav los ntawm ib tug transversal thiaj li hais tias (lwm sab hauv, alternate sab nrauv, coj) lub kaum sab xis yog congruent, ces tus kab yog thaum uas tig mus.
Ib sab ntawm qhov no, koj ua li cas ua pov thawj ob kab sib npaug tsis muaj kaum?
Yog ob kab muaj ib tug transversal uas tsim lwm sab hauv lub kaum sab xis uas yog congruent, ces tus ob kab yog parallel . Yog ob kab muaj ib tug transversal uas cov ntaub ntawv sib raug lub kaum sab xis uas yog congruent, ces tus ob kab yog parallel.
Puas yog cov kab sib txuas sib txuas?
Yog ob kab sib npaug yog txiav los ntawm ib tug transversal, alternate sab hauv ces kaum yog kev sib haum xeeb . Yog ob kab yog txiav los ntawm ib tug transversal thiab alternate sab hauv cov ces kaum yog kev sib haum xeeb , cov kab yog parallel.

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
Txoj kev faib cov ntaub ntawv twg muab cov ntaub ntawv sib npaug ntawm cov ntaub ntawv lossis cov kev tshuaj xyuas hauv txhua chav kawm cov ntaub ntawv?
Quantile. txhua chav kawm muaj cov yam ntxwv sib npaug. Ib qho kev faib tawm ntau yog zoo haum rau cov ntaub ntawv faib tawm. Quantile muab tib tus lej ntawm cov ntaub ntawv muaj nuj nqis rau txhua chav kawm
Puas yog cov kab sib txuas ua pov thawj cov kab sib txuas?
Thawj yog yog tias cov ces kaum sib thooj, cov ces kaum uas nyob rau tib lub ces kaum ntawm txhua qhov kev sib tshuam, yog sib npaug, ces cov kab sib npaug. Qhov thib ob yog yog tias qhov sib txawv sab hauv lub kaum sab xis, cov ces kaum uas nyob rau sab nraud ntawm lub transversal thiab sab hauv cov kab sib npaug, sib npaug, ces cov 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
