Lub voj voog ntawm lub voj voog voj voog yog lub vojvoog ntawm lub voj voog ncig ntawm lub polygon. Rau ib daim duab peb sab, nws yog qhov ntsuas ntawm lub vojvoog ntawm lub voj voog uas circumscribes daim duab peb sab. Vim txhua daim duab peb sab yog cyclic, txhua daim duab peb sab muaj lub voj voog ncig, lossis ib ncig.
Puas txhua daim duab peb sab muaj ib ncig?
Theorem: Txhua daim duab peb sab yog cyclic, i.e. txhua daim duab peb sab muaj lub voj voog ncig lossis ncig… Daim duab peb sab ob sab thiab sib tshuam sab ntawd ntawm nws qhov nruab nrab.) Cov bisectors no yuav sib tshuam ntawm ib qho taw tes O.
Daim duab peb sab puas tsis muaj lub voj voog?
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 hauv 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 koj thiaj paub yog daim duab peb sab yog circumcenter?
txhawm rau nrhiav qhov ncig ntawm ib daim duab peb sab, kos cov kab sib txuas ntawm ob sab thiab txuas rau lawv. Lub ntsiab lus ntawm qhov perpendicular sib tshuam ib leeg yuav yog qhov chaw ntawm daim duab peb sab.
Yuav ua li cas 3 yam ua ib ncig?
Ntau qhov pov thawj qhia tias ib qho taw tes yog nyob rau ntawm ib qho kev sib txuas ntawm ib ntu yog tias thiab tsuas yog qhov sib npaug ntawm qhov kawg. Siv qhov no los tsim lub voj voog, circumradius, thiab voj voograu daim duab peb sab.
