Theorem: Txhua daim duab peb sab yog voj voog, piv txwv li txhua daim duab peb sab muaj circumscribed voj voog los yog voj voog.
Daim duab peb sab puas tsis muaj qhov ntsuas qhov ntsuas?
Lub voj voog tsis yog ib txwm nyob hauv daim duab peb sab. Qhov tseeb, nws tuaj yeem nyob sab nraud ntawm daim duab peb sab, xws li nyob rau hauv rooj plaub ntawm daim duab peb sab obtuse, lossis nws tuaj yeem poob ntawm qhov nruab nrab ntawm lub hypotenuse ntawm daim duab peb sab. Saib cov duab hauv qab no rau cov piv txwv ntawm qhov no.
Yuav ua li cas 3 yam ua ib ncig?
Lub Circumcenter ntawm daim duab peb sab
Lub ntsiab lus uas peb lub voj voos ntawm daim duab peb sab sib ntsib. Ib qho ntawm daim duab peb sab cov ntsiab lus ntawm concurrency.
Dab tsi daim duab peb sab muaj ib ncig?
Properties of Circumcenter
In an acute-angled triangle, circumcenter lies nyob rau hauv daim duab peb sab. Hauv daim duab peb sab obtuse-angled, nws nyob sab nraum daim duab peb sab. Circumcenter nyob ntawm qhov nruab nrab ntawm lub hypotenuse sab ntawm daim duab peb sab sab xis.
Pob daim duab peb sab obtuse muaj ib ncig?
Lub voj voog ntawm daim duab peb sab obtuse ib txwm nyob sab nraum daim duab peb sab. Lub voj voog ntawm ib daim duab peb sab yog sab hauv, ntawm, lossis sab nraud ntawm daim duab peb sab, thiab nws txav mus thiab nqis. 4. INCENTER(I) ntawm daim duab peb sab yog qhov taw tes rau sab hauv ntawm daim duab peb sab uas yog sib npaug ntawm peb sab.

Puas yog trigonometry ua haujlwm ntawm txhua daim duab peb sab?
Kev piav qhia: Txawm hais tias feem ntau cov haujlwm trigonometric yog siv nrog cov duab peb sabmuaj qee qhov xwm txheej thaum lawv tuaj yeem siv rau txhua hom duab peb sab. … Yog tias koj muaj ob sab muab thiab ib lub kaum sab xis ntawm lawv koj tuaj yeem siv txoj haujlwm trigonometric txoj cai lij choj ntawm Cosines los suav rau sab thib peb.
Lub kaum sab xis twg tuaj yeem tsim daim duab peb sab?
Daim duab peb sab kuj tuaj yeem raug cais los ntawm lawv cov kaum. Hauv daim duab peb sab mob daim duab peb sab tag nrho peb lub kaum sab xis yog mob (tsawg dua 90 degrees). Daim duab peb sab txoj cai muaj ib lub kaum sab xis thiab ob lub kaum sab xis.
Puas yog daim duab peb sab nrog ob sab sib npaug?
Isosceles Isosceles. Daim duab peb sab isosceles tuaj yeem kos rau ntau txoj hauv kev. Nws tuaj yeem kos kom muaj ob sab sib npaug thiab ob lub kaum sib npaug lossis nrog ob lub kaum ntse ntse thiab ib lub kaum obtuse. Nws yog ib qho yooj yim los ua kom tiav cov ces kaum uas ploj lawm ntawm daim duab peb sab isosceles los ntawm kev nrhiav cov ces kaum uas yuav tsum sib npaug.
Thaum twg peb xav txog daim duab peb sab ua equiangular?
Ib daim duab peb sab uas nws tag nrho peb sab thiab sab hauv cov ces kaum sib npaug yog hu ua daim duab peb sab equiangular. Rau ib daim duab peb sab kom sib npaug, qhov ntsuas ntawm tag nrho nws peb lub kaum sab hauv yuav tsum sib npaug li 60 degrees.
Puas yog txhua daim duab peb sab sib npaug?
Ib daim duab peb sab sib npaug yog daim duab peb sab uas nws ob sab sib npaug. … Yog li ntawd, txij li tag nrho peb sab ntawm daim duab peb sab sib npaug sib npaug, tag nrho peb lub kaum sab xis sib npaug, ib yam nkaus. Li no, txhua daim duab peb sab sib npaug kuj yog qhov sib npaug.
