Ob lub kaum sab xis yog Ntxiv thaum lawv nce mus txog 180 degrees. Lawv tsis tas yuav nyob ib sab ntawm ib leeg, tsuav yog tias tag nrho yog 180 degrees. Piv txwv li: • 60 ° thiab 120 ° yog ntxiv lub kaum sab xis.
Tsuas yog li ntawd, puas yog daim duab peb sab ntxiv lossis ntxiv?
Qhov mob lub kaum sab xis ntawm ib daim duab peb sab yog complementary. Qhov sum ntawm lub kaum sab xis hauv daim duab peb sab ntxiv rau 180º. Tom qab rho tawm 90º rau txoj cai lub kaum sab xis , muaj 90º sab laug rau ob qhov mob lub kaum sab xis , ua rau lawv complementary. Ntxiv Lub kaum sab xis yog ob lub kaum sab xis tus lej ntawm nws qhov ntsuas yog 180º.
Tsis tas li ntawd, dab tsi yog qhov txawv ntawm kev ntxiv thiab ntxiv? Ob lub tswv yim uas muaj feem cuam tshuam tab sis tsis zoo ib yam ntxiv kaum thiab ntxiv lub kaum sab xis. Cov txawv yog lawv sum. Ntxiv Lub kaum sab xis yog ob lub kaum ntse ntse uas ntsuas qhov ntsuas ntawm 180 degrees thiab ntxiv yog cov lej yuav tsum tau ntxiv mus txog 90 degrees. Thiab kuv tau sau tseg ntawm no tias cov no tsis tas yuav nyob ib sab.
Ib yam li ntawd, qhov ntxiv txhais li cas hauv geometry?
Ob lub kaum sab xis Ntxiv thaum lawv nce mus txog 180 degrees. Ob lub kaum sab xis (140 ° thiab 40 °) yog Ntxiv Lub kaum sab xis, vim lawv ntxiv txog 180 °: Daim ntawv ceeb toom tias ua ke lawv ua lub kaum sab xis. Tab sis cov ces kaum tsis tas yuav ua ke.
Puas muaj 3 lub kaum sab xis ntxiv?
Qhov thib peb txheej muaj peb lub ces kaum uas sum rau 180 °; peb lub ces kaum ua tsis tau ntxiv.

Dab tsi yog equidistant los ntawm peb sab ntawm daim duab peb sab?
Lub ntsiab lus uas sib npaug rau txhua sab ntawm daim duab peb sab yog hu ua incenter: Ib qho nruab nrab yog ib qho kab uas muaj ib qho ntawm nws qhov kawg ntawm lub vertex ntawm daim duab peb sab thiab lwm qhov kawg ntawm qhov nruab nrab ntawm sab opposite lub vertex. Peb qhov nruab nrab ntawm ib daim duab peb sab sib ntsib hauv centroid
Dab tsi yog lub kaum sab xis ntsuas hauv daim duab peb sab ABC?
Kev piav qhia ib kauj ruam dhau los: Nws tau muab tias ABC yog lub kaum sab xis uas yog kaum sab xis ntawm C thiab AC = 7 ntiv tes thiab CB = 5 ntiv tes. Yog li, qhov ntsuas ntawm cov kaum sab xis uas ploj lawm hauv daim duab peb sab ABC yog 35.5 ° thiab 54.5 ° feem
Koj tuaj yeem ua pov thawj li cas 2 daim duab peb sab zoo sib xws siv lub kaum sab xis sab SAS zoo sib xws postulate?
SAS Similarity Theorem hais tias yog ob sab hauv ib daim duab peb sab yog proportional rau ob sab hauv lwm daim duab peb sab thiab lub kaum sab xis nyob rau hauv ob qho tib si congruent, ces ob daim duab peb sab zoo ib yam. Ib qho kev hloov pauv zoo sib xws yog ib lossis ntau qhov kev hloov pauv tsis tu ncua ua raws li kev dilation
Vim li cas nws thiaj li hais tias lub Orthocenter ntawm daim duab peb sab obtuse yuav tsum nyob rau sab nraud ntawm daim duab peb sab?
Nws hloov tawm tias tag nrho peb qhov siab ib txwm sib tshuam ntawm tib lub ntsiab lus - lub npe hu ua orthocenter ntawm daim duab peb sab. Lub orthocenter tsis yog ib txwm nyob hauv daim duab peb sab. Yog tias daim duab peb sab yog obtuse, nws yuav nyob sab nraud. Txhawm rau ua kom qhov no tshwm sim cov kab qhov siab yuav tsum tau txuas ntxiv kom lawv hla
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
