Tib sab sab hauv cov ces kaum yog nyob rau tib sab ntawm transversal. Tib sab sab hauv cov ces kaum yog kev sib haum xeeb thaum kab yog parallel.
Raws li kev sib raug zoo, puas yog tib sab sab hauv cov ces kaum ntxiv lossis congruent?
Tib sab sab hauv cov ces kaum yog ob lub kaum sab xis uas yog nyob rau tib sab ntawm transversal thiab ntawm lub sab hauv ntawm (nruab nrab) ob kab. Tib Sab Sab Hauv Lub Kaum Theorem: Yog hais tias ob kab sib npaug yog txiav los ntawm ib qho transversal, ces tus tib sab sab hauv cov ces kaum yog ntxiv.
Dab tsi yog tib sab sab hauv lub kaum sab xis? Cov ib yam - sab sab hauv lub kaum sab xis theorem hais tias thaum ob kab uas yog parallel yog intersected los ntawm ib tug transversal kab, lub ib yam - sab sab hauv cov ces kaum uas yog tsim yog ntxiv, los yog ntxiv rau 180 degrees.
Tsuas yog li ntawd, tib lub kaum sab xis puas sib haum?
Ib yam - sab sab hauv lub kaum sab xis tsis yog ib txwm sib haum xeeb . Qhov tseeb, tib lub sij hawm lawv yog kev sib haum xeeb (hais tias lawv muaj ib yam ntsuas) yog thaum lub
Puas yog linear khub sib haum?
A linear khub txhais tau hais tias cov ces kaum nyob ib sab thiab tsim ib txoj kab ncaj nraim (thiab ib txwm ntxiv). Cov kaum sab xis ntxiv ntxiv txog 180, tab sis tsis tas yuav nyob ib sab. Vertical angles yog cov kaum sab xis uas tsim los ntawm cov kab sib tshuam. Lawv yeej ib txwm kev sib haum xeeb tab sis TSIS ib txwm complementary.

Puas yog chimpanzees thiab tib neeg nyob hauv tib genus?
Tib neeg thiab chimpanzees yuav tsum tau muab tso rau hauv tib lub genus, Homo, raws li WSU cov kws tshawb fawb hauv tsab xov xwm Tsib Hlis 19 (#2172) luam tawm hauv Kev Ua Haujlwm ntawm National Academy of Sciences. Cov kev hloov pauv hauv qhov kev txiav txim thawj zaug tau ua rau muaj kev sib cav txog kev hloov pauv
Puas yog lub kaum sab xis sab congruent?
Lub Side Angle Side postulate (feem ntau abbreviated li SAS) hais tias yog ob sab thiab lub kaum sab xis ntawm ib daim duab peb sab yog congruent rau ob sab thiab lub kaum sab xis ntawm lwm daim duab peb sab, ces ob daim duab peb sab yog congruent
Puas yog tib sab sab nrauv cov ces kaum ntxiv?
Ob lub kaum sab nrauv sab nrauv rau cov kab sib txuas thiab ntawm tib sab ntawm txoj kab transversal yog hu ua tib-sab sab nrauv cov ces kaum. Lub theorem hais tias tib lub sab sab nrauv cov ces kaum yog ntxiv, txhais tau tias lawv muaj qhov sib npaug ntawm 180 degrees
Dab tsi yog kev sib raug zoo ntawm sab nrauv thiab sab hauv lub kaum sab xis ntawm daim duab peb sab?
Cov kaum sab hauv yog hu ua Sab hauv cov ces kaum. Cov lej ntawm cov kaum sab hauv ntawm daim duab peb sab yog ib txwm 180 degrees. Lub kaum sab nrauv yog lub kaum sab xis ntawm ib sab ntawm ib qho duab, thiab ib txoj kab txuas ntxiv los ntawm sab tom ntej. Qhov sib npaug ntawm lub kaum sab nrauv thiab nws lub kaum sab hauv uas nyob ib sab kuj yog 180 degrees
Puas yog daim duab peb sab congruent muaj tib lub perimeter?
Yog tias ob daim duab peb sab sib npaug, ces txhua feem ntawm daim duab peb sab (sab los yog lub kaum sab xis) yog congruent rau qhov sib thooj hauv lwm daim duab peb sab. Ntxiv rau ob sab thiab cov ces kaum, tag nrho lwm yam khoom ntawm daim duab peb sab yog tib yam, xws li thaj tsam, ib puag ncig, qhov chaw ntawm cov chaw, lub voj voog thiab lwm yam
