Teb thiab piav qhia: Ib lub kaum sab xis uas ntsuas raws nraim 180 degrees yog hu ua ' ncaj lub kaum sab xis.
Ib yam li ib tug yuav nug, qhov 180 degree lub kaum sab xis zoo li cas?
Nws yog sib npaug rau ib feem peb ntawm ib qho kev sib hloov nyob ib ncig ntawm lub voj voog. Ib txoj kab ncaj nraim tsim ib 180 degree kaum sab xis . Nws yog sib npaug rau ib nrab ib ncig ntawm ib lub voj voog.
Tsis tas li ntawd, qhov sib npaug ntawm qhov ntsuas ntawm cov kaum hauv ib daim duab peb sab yog 180 degrees? Cov Daim duab peb sab Theorem hais tias peb sab hauv lub kaum sab xis ntawm tej daim duab peb sab ntxiv rau 180 degrees.
Hauv qhov no, lub kaum sab xis ntsuas yog dab tsi?
Hauv geometry, ib lub kaum sab xis ntsuas tuaj yeem txhais raws li qhov ntsuas ntawm lub kaum sab xis tsim los ntawm ob lub rays los yog caj npab ntawm ib qho vertex. Lub kaum sab xis ntsuas nyob rau hauv degrees (°), siv lub protractor.
Lub kaum sab xis 45 degree zoo li cas?
45 - Lub kaum sab xis . Ib ncaj lub kaum sab xis ntsuas 180 °. Ib lub kaum sab xis tuaj yeem ntsuas tau siv tus protractor, thiab lub kaum sab xis ua 90 qib hu ua txoj cai lub kaum sab xis . Nyob rau hauv ib txoj cai lub kaum sab xis , ob txhais tes yog perpendicular rau ib leeg.

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
Cov kab lus hloov sab hauv cov ces kaum piav qhia txoj haujlwm ntawm ob lub kaum sab xis li cas?
Hloov sab hauv cov ces kaum yog tsim los ntawm ib tug transversal intersecting ob parallel kab. Lawv nyob nruab nrab ntawm ob qho tib si kab tab sis nyob rau sab nraud ntawm lub transversal, tsim ob khub (plaub tag nrho cov ces kaum) ntawm cov ces kaum sab hauv. Hloov cov ces kaum sab hauv yog congruent, txhais tau tias lawv muaj qhov sib npaug
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
Dab tsi yog txoj cai kaum rau lwm lub kaum sab xis?
Hloov cov ces kaum sab hauv yog tsim thaum lub transversal hla dhau ob kab. Lub kaum sab xis uas tsim nyob rau sab nraud ntawm lub transversal thiab sab hauv ob kab yog alternate sab hauv cov ces kaum. Lub theorem hais tias thaum cov kab sib npaug, qhov sib txawv sab hauv cov ces kaum sib npaug
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
