Video: Yuav ua li cas koj daws cov khoom ntawm parallelogram?
2024 Tus sau: Taylor Roberts | [email protected]. Kawg hloov kho: 2023-12-16 00:29
Properties ntawm parallelograms
- Cov sab nraud yog congruent (AB = DC).
- Cov tubtxib saum ntuj yog congruent (D = B).
- Cov ces kaum sib ntxiv yog ntxiv (A + D = 180 °).
- Yog tias ib lub kaum sab xis yog qhov zoo, ces txhua lub ces kaum yog txoj cai.
- Diagonals ntawm a parallelogram sib cais.
- Txhua kab pheeb ces kaum ntawm a parallelogram cais nws ua ob daim duab peb sab sib xws.
Hauv qhov no, 4 yam khoom ntawm parallelograms yog dab tsi?
Cov ntsiab lus ntawm cov khoom
| S. Tsis Yog | Khoom | Parallelogram |
|---|---|---|
| 2 | Cov sab nraud yog sib npaug thiab sib npaug | ✓ |
| 3 | Tag nrho cov ces kaum yog congruent | ✕ |
| 4 | Cov kaum sab nraud yog congruent | ✓ |
| 5 | Diagonals yog congruent | ✕ |
Ib yam li ntawd, 6 lub zog ntawm parallelogram yog dab tsi? Muaj rau qhov tseem ceeb ntawm parallelograms kom paub: Cov sab nraud yog congruent (AB = DC). Cov tim tswv sib txawv yog sib haum (D = B). Sib txuas lub kaum sab xis yog ntxiv (A + D = 180 °).
Tom qab ntawd, 5 yam khoom ntawm daim duab sib dhos yog dab tsi?
Cov ntsiab lus hauv txheej no (5)
- Ob khub ntawm ob sab sib luag yog sib luag.
- Ob leeg ntawm opposite sab yog congruent.
- Ob khub ntawm cov ces kaum sib txawv yog sib xws.
- Cov kaum sib law liag yog ntxiv.
- Diagonals sib sib zog nqus.
Koj yuav daws cov cuab yeej ntawm lub quadrilateral li cas?
Muaj ob cov khoom ntawm quadrilaterals : A quadrilateral yuav tsum kaw zoo li 4 sab. Tag nrho cov kaum sab hauv ntawm a quadrilateral sum txog 360 °
Parallelogram
- Cov kaum sab xis sib npaug.
- Ob sab sib npaug thiab sib luag.
- Diagonals bisect ib leeg.
- Qhov sib npaug ntawm ob lub kaum sab xis yog 180 °

Koj yuav siv cov khoom sib txuas hauv cov kav dej li cas?
Compression fittings ua hauj lwm los ntawm compression ntawm ib tug 'txiv ntseej' ntawm ob tapered nto thiab cov yeeb nkab nws tus kheej. Ob lub ntsej muag yog lub cev haum (ua nws lub valve, txuas lossis lwm yam) thiab txiv ntoo. Siv ib tug spanner thiab ib tug khub ntawm tuav lub txiv ntseej yog nruj nreem
Ntev npaum li cas koj yuav tsum rov ntim cov log bearings ntawm lub tsheb thauj khoom siv hluav taws xob?
Qee cov tuam ntxhab pom zoo tshuaj xyuas thiab pleev xim rau RV lub log log ib zaug txhua lub caij, lossis tsawg kawg txhua 10,000 mais. Tab sis lub nkoj thauj khoom nrog lub log me me yuav tsum rov ntim txhua 2,000 mais. Feem ntau, lub log me me, lub log nrawm dua, uas ua rau muaj kev ntxhov siab rau cov bearings
Koj yuav tshem tawm cov xov hluav taws xob los ntawm tus muag khoom lub hau li cas?
Thaum tshem cov xov hlau los ntawm lub taub hau los yog lub hau npog, twist lossis tig lub khau raj kom loosen nws ntawm lub ntsaws. Tsis txhob rub lossis rub rau ntawm cov xaim lossis koj tuaj yeem tsoo qhov kev sib txuas. Nco ntsoov tsuas rub rau ntawm khau raj; tsis txhob rub lub cable nws tus kheej
Koj yuav daws teeb meem qhov ntsuas roj siab li cas?
VIDEO Ib yam li ntawd, kuv yuav ua li cas thiaj paub yog tias kuv lub ntsuas ntsuas roj tsis zoo? Cov tsos mob ntawm a phem roj siab ntsuas Muaj ib tug kws kho tsheb xyuas cov roj qib. Roj ntsuas ntsuas nyeem ntawv tsawg dhau, feem ntau qis dua 15 mus rau 20 PSI thaum idling.
Koj puas tuaj yeem tau txais ua ntej ntawm koj qhov kev hais daws?
Kev them nyiaj ua ntej muab nyiaj ntsuab rau koj uas koj xav tau los them koj cov nuj nqis nyob thiab cov nqi them ua ntej kev txiav txim raug txiav txim lossis rooj plaub raug txiav txim. Koj tuaj yeem siv cov nyiaj los them koj cov nqi xauj tsev lossis tsev qiv nyiaj, them tsheb, nqi kho mob lossis txawm tias khoom noj khoom haus. Kev ua ntej yog koj li siv raws li koj xav tau
