Cov Lub kaum sab xis postulate (feem ntau abbreviated li AAS) hais tias yog ob cov ces kaum thiab tsis suav nrog sab ib daim duab peb sab congruent rau ob cov ces kaum thiab cov tsis suav nrog sab ntawm lwm daim duab peb sab, tom qab no ob daim duab peb sab yog sib xws.
Ib sab ntawm qhov no, koj puas tuaj yeem ua pov thawj daim duab peb sab congruent los ntawm AAS?
Cov AAS Theorem hais tias: Yog ob lub kaum thiab tsis suav nrog sab ntawm ib daim duab peb sab yog kev sib haum xeeb mus rau qhov sib thooj ntawm lwm tus daim duab peb sab , cov daim duab peb sab yog kev sib haum xeeb.
Qhov thib ob, ua li cas koj paub thaum daim duab peb sab yog congruent? Ob daim duab peb sab yog kev sib haum xeeb yog tias lawv muaj: raws nraim tib yam peb sab thiab. raws nraim tib lub ces kaum.
Muaj tsib txoj hauv kev los nrhiav yog ob daim duab peb sab sib xws: SSS, SAS, ASA, AAS thiab HL.
- SSS (sab, sab, sab)
- SAS (sab, kaum sab xis, sab)
- ASA (lub kaum sab xis, sab, kaum sab xis)
- AAS (kaum, kaum, sab)
- HL (hypotenuse, ceg)
Tom qab ntawd, lo lus nug yog, koj yuav qhia li cas yog daim duab peb sab yog ASA lossis AAS?
– ASA thiab AAS yog ob qho kev tshaj tawm uas pab peb txiav txim yog tias ob daim duab peb sab yog concruent. ASA stands rau "Angle, Side, Angle", hos AAS txhais tau tias "Angle, Angle, Side". Ob daim duab zoo sib xws yog lawv yog cov zoo tib yam thiab loj. Hauv lwm lo lus, ob daim duab sib dhos yog ib qho thiab tib daim duab, hauv ob qhov chaw sib txawv.
SSS SAS ASA AAS yog dab tsi?
SSS (sab-sab-sab) Tag nrho peb sab sib xws yog sib haum. SAS (sab-angle-sab) Ob sab thiab lub kaum sab xis ntawm lawv yog congruent. ASA (angle-sib-angle)

Dab tsi yog qhov tseem ceeb ntawm daim duab peb sab anterior ntawm lub caj dab?
Muaj ntau qhov teeb meem vascular tseem ceeb hauv daim duab peb sab ua ntej. Feem ntau cov hlab ntsha carotid bifurcates nyob rau hauv daim duab peb sab mus rau sab nraud thiab sab hauv carotid ceg. Internal jugular vein kuj tuaj yeem pom nyob rau hauv cheeb tsam no - nws yog lub luag haujlwm rau venous kua ntawm lub taub hau thiab caj dab
Peb ciam teb ntawm daim duab peb sab ntawm Calot yog dab tsi?
Daim duab peb sab ntawm Calot yog ib qho tseem ceeb thaj chaw uas nws ciam teb muaj xws li cov kab mob hepatic medially, lub cystic duct tom qab, thiab cov ntug qis ntawm lub siab zoo dua
Cov kab mob sib koom ua ke twg yog tus cwj pwm los ntawm kev sib koom ua ke ntawm kev txav mus los thiab kev sib koom ua ke ntawm qhov hnyav ntawm cov pob qij txha uas feem ntau yog relieved los ntawm so?
Osteoarthritis feem ntau cuam tshuam rau txhais tes, qis nraub qaum, caj dab, thiab hnyav sib koom tes xws li hauv caug, lub duav, thiab ko taw
Cov khub twg ntawm daim duab peb sab tuaj yeem ua pov thawj sib haum siv hypotenuse leg Theorem?
The hypotenuse leg theorem hais tias txhua ob txoj cai peb tog uas muaj qhov sib thooj hypotenuse sib xws thiab sib thooj, sib koom ua ke ceg yog daim duab peb sab sib luag
Dab tsi yog 5 txoj hauv kev los ua pov thawj daim duab peb sab sib npaug?
Muaj tsib txoj hauv kev los nrhiav yog ob daim duab peb sab sib xws: SSS, SAS, ASA, AAS thiab HL. SSS (sab, sab, sab) SSS sawv rau 'sab, sab, sab' thiab txhais tau tias peb muaj ob daim duab peb sab nrog txhua peb sab sib npaug. SAS (sab, kaum, sab) ASA (lub kaum sab xis, sab, lub kaum sab xis) AAS (lub kaum sab xis, lub kaum sab xis, sab) HL (hypotenuse, ceg)
