Cov Daim duab peb sab Inequality Theorem hais tias: Ib sab ntawm ib daim duab peb sab yuav tsum luv dua li ob sab ntxiv ua ke. Yog tias ntev dua, ob tog yuav tsis sib ntsib! Sim txav cov ntsiab lus hauv qab no: 208 tsawg dua 203 + 145 = 348.
Kuj paub, dab tsi yog daim duab peb sab inequality theorem?
Cov Formula The Daim duab peb sab Inequality Theorem hais tias qhov sum ntawm 2 sab ntawm a daim duab peb sab yuav tsum ntau tshaj qhov ntsuas ntawm sab thib peb. Nco tseg: Txoj cai no yuav tsum txaus siab rau tag nrho 3 yam xwm txheej ntawm sab.
Ib yam li ntawd, txoj cai 3 4 5 Daim duab peb sab yog dab tsi? Cov 3 : 4 : 5 daim duab peb sab yog qhov zoo tshaj plaws uas kuv paub los txiav txim nrog qhov tseeb tias lub kaum sab xis yog 90 degrees. Qhov no txoj cai hais tias yog ib sab ntawm ib daim duab peb sab ntsuas 3 thiab cov kev ntsuas uas nyob ib sab 4 , ces lub diagonal ntawm ob lub ntsiab lus yuav tsum ntsuas 5 kom nws yog txoj cai daim duab peb sab.
Nyob rau hauv no hais txog, yog vim li cas daim duab peb sab inequality theorem muaj tseeb?
Cov daim duab peb sab inequality theorem hais tias qhov ntev ntawm ib sab ntawm a daim duab peb sab yuav tsum luv dua qhov ntev ntawm ob sab ntxiv ua ke. Qhov no yog vim cov kab ntu no txaus siab rau daim duab peb sab inequality theorem.
Dab tsi yog qhov sum ntawm tag nrho 3 sab ntawm daim duab peb sab?
Hauv Euclidean qhov chaw, lub sum ntawm kev ntsuas ntawm cov no peb cov ces kaum ntawm tej daim duab peb sab yog invariably sib npaug rau lub kaum sab xis, kuj qhia raws li 180 °, π radians, ob txoj cai kaum, los yog ib nrab-tig. Nws tsis paub ntev txog seb puas muaj lwm cov geometry, nyob qhov twg sum yog txawv.

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
