- Cov kab pheeb ces kaum ntawm qhov kev tsim lej no sib tshuam tsuas yog ntawm cov ces kaum sab xis thiab muab faib ua ib nrab ntawm qhov kev sib tshuam. Ntawd yog, cov kab pheeb ces kaum faib lub rhombus rau hauv plaub daim duab peb sab sib npaug.
- Lub kaum ob sab yog raws kab pheeb ces kaum.
- Tus lej ntawm cov squares ntawm kab pheeb ces kaum sib npaug ntawm cov square ntawm sab muab faib ua plaub.
- Cov vertices ntawm daim duab plaub yog qhov nruab nrab ntawm plaub sab ntawm qhov kev tsim kho no hu ua rhombus.
- Cov kab pheeb ces kaum ntawm daim duab yog qhov perpendicular rau lawv axes ntawm symmetry.
- Ib lub voj voog nrog qhov chaw pw ntawm qhov kev sib tshuam tuaj yeem sau rau hauv ib daim duab hu ua rhombus.
- Dab tsi yog kab pheeb ces kaum ntawm lub rhombus? Nov yog txoj kab uas txuas nws cov ces kaum.
Cov cim ntawm pob zeb diamond
Peb kawm paub tias lub rhombus yog dab tsi, tab sis ntxiv rau cov khoom ntawm daim duab no, kuj muaj cov cim qhia. Ib qho parallelogram yuav yog lub rhombus yog tias nws ua tiav yam tsawg kawg ib qho ntawm cov xwm txheej hauv qab no:
- Ob sab ntawm lub rhombus sib npaug sib luag.
- Cov kab pheeb ces kaum ntawm qhov kev tsim lej no tsuas yog sib tshuam ntawm cov ces kaum sab xis thiab tsis muaj dab tsi ntxiv.
- Ib qho ntawm kab pheeb ces kaum yuav tsum muab faib ua txhua qhov chaw uas nws muaj.
- Thiab yog peb xav tias pebNws tsis paub tias cov plaub hau plaub hau yog ib qho parallelogram, tab sis nws paub tias ob sab ntawm daim duab yog sib npaug, ces peb tuaj yeem ntseeg tau hais tias: plaub plaub fab yog lub rhombus.
- Ntawm no yog ib feem ntawm txoj kab uas tsim ib lub kaum sab xis sib npaug li 90 degrees thaum hla qhov ntxeev sab.
- Dab tsi yog qhov siab ntawm pob zeb diamond? Qhov no yog ib feem ntawm txoj kab uas ua rau lub kaum sab xis 90 degree thaum nws hla mus rau sab nraud.
Rhombus area
Peb paub tias lub rhombus yog dab tsi, nws cov khoom thiab cov cim qhia dab tsi, tab sis yuav ua li cas thiaj nrhiav tau nws thaj chaw? Txhawm rau nrhiav thaj tsam ntawm lub rhombus, faib cov khoom ntawm kab pheeb ces kaum ntawm daim duab no ib nrab. Txij li thaum lub rhombus yog tib lub parallelogram, thaj tsam ntawm xws li kev tsim ua lej yog sib npaug rau cov khoom ntawm qhov siab thiab qhov ntev ntawm nws sab. Tsis tas li ntawd, thaj tsam ntawm daim duab tuaj yeem pom thaum suav nrog cov qauv uas nyob ib sab lossis nrog lub vojvoog ntawm lub voj voog inscribed. Lub vojvoog ntawm lub voj voog inscribed yog qhia nyob rau hauv cov nqe lus ntawm diagonals. Txhawm rau xam qhov ib puag ncig ntawm lub rhombus, muab qhov ntev ntawm ib qho ntawm plaub sab los ntawm plaub.
Thiab thiaj li yuav piav txog daim duab no hauv daim duab, koj yuav tsum ua raws li cov lus qhia hauv qab no. Tom qab tag nrho, thaum tsim daim duab no, ntau tus muaj teeb meem. Yog li, txhawm rau kom paub meej txog lub rhombus, koj yuav tsum xub kos thawj kab pheeb ces kaum, tom qab ntawd txuas rau qhov thib ob, thiab thaum kawg txuas cov npoo ntawm ntu. Koj yuav tsum kos daim duab no kom zoo zoo thiab ua tib zoo kom tsis txhob kos ib lub square.
