Ib daim duab peb sab isosceles yog li ntawd muaj ob sab sib npaug thiab ob lub kaum sib npaug … Daim duab peb sab nrog txhua sab sib npaug yog hu ua daim duab peb sab sib npaug, thiab daim duab peb sab uas tsis muaj sab sib npaug yog hu ua daim duab peb sab scalene.
Vim li cas isosceles daim duab peb sab tsis zoo sib xws?
Txhua daim duab peb sab isosceles tsis zoo sib xws rau ob peb yam. Qhov ntev ntawm ob sab sib npaug tuaj yeem nyob tib yam tab sis qhov ntsuas ntawm lub kaum sab xis ntawm ob sab sib npaug yuav hloov pauv, raws li lub hauv paus thiab lub hauv paus kaum.
Dab tsi yog hu ua daim duab peb sab isosceles?
Nyob hauv daim duab peb sab isosceles uas muaj ob sab sib npaug, sab sib npaug yog hu ua cegthiab sab thib peb hu ua lub hauv paus. Lub kaum sab xis suav nrog ob txhais ceg yog hu ua lub kaum sab xis thiab cov kaum sab xis uas muaj lub hauv paus raws li ib qho ntawm lawv sab yog hu ua lub kaum sab xis. Lub vertex opposite lub hauv paus yog hu ua lub apex.
Vim li cas daim duab peb sab isosceles muaj ob lub kaum sib npaug?
In isosceles triangles cov ces kaum ntawm lub hauv paus yog sib npaug rau ib leeg, thiab, yog tias cov kab ncaj ncaj sib npaug tau tsim ntxiv, cov ces kaum hauv qab yuav sib npaug rau txhua tus. lwm yam.
Vim li cas daim duab peb sab sib npaug kuj yog isosceles?
Txhua daim duab peb sab sib npaug kuj yog daim duab peb sab isosceles, yog li ob sab uas sib npaug muaj qhov sib npaug ntawm cov kaum sab xis… peb lub ces kaum sib npaug, ib yam nkaus. Li no, txhua daim duab peb sab sib npaug kuj yog equiangular.

Ob lub kaum sab nraud ntawm ob lub cim ob sab kuj zoo ib yam: ob lub kaum sab xis yog 70 ° Tag nrho peb lub kaum sab hauv sab hauv lub kaum sab xis Qhov ntsuas ntawm lub kaum sab nrauv ntawm lub vertextsis cuam tshuam los ntawm sab twg yog txuas ntxiv :
Qhov twg yog qhov hypotenuse ntawm daim duab peb sab isosceles?
Yog, lub hypotenuse yog ib txwm yog sab ntev tshaj, tab sis tsuas yog rau txoj cai kaum sab xis. Rau cov duab peb sab isosceles, ob sab sib npaug yog hu ua ob txhais ceg, thaum nyob rau hauv daim duab peb sab sib npaug txhua sab yog paub yooj yim li ob sab .
Puas yog daim duab peb sab isosceles muaj cov kaum sib npaug?
Ib daim duab peb sab isosceles yog li ntawd muaj ob sab sib npaug thiab ob lub kaum sib npaug Lub npe muab los ntawm Greek iso (tib yam) thiab skelos (ceg). Daim duab peb sab nrog txhua sab sib npaug yog hu ua daim duab peb sab sib npaug, thiab daim duab peb sab uas tsis muaj sab sib npaug yog hu ua daim duab peb sab scalene .
