Parallel kab yog kab nyob rau hauv ib lub dav hlau uas ib txwm sib nrug deb. Parallel kab yeej tsis sib tshuam. Perpendicular kab yog kab uas sib tshuam ntawm txoj cai (90 degrees) lub kaum sab xis.
Kuj paub, qhov sib txawv ntawm cov kab sib luag thiab kab perpendicular yog dab tsi?
Ob kab hais tias yog thaum uas tig mus thaum lawv sib npaug ntawm ib leeg thiab yuav tsis cuam tshuam lossis kov. Hauv cov ntsiab lus yooj yim, txoj kab nqes ntawm ob kab sib npaug yog sib npaug. Txoj kab nqes ntawm kab perpendicular , ntawm qhov tod tes, yog qhov tsis zoo reciprocals ntawm ib leeg lub ntsiab lus kab hla ib leeg ntawm lub kaum sab xis.
Tom qab ntawd, lo lus nug yog, dab tsi yog cov kab sib txuas thiab kab perpendicular ks2? Parallel kab yeej ib txwm sib nrug deb ntawm lawv tag nrho ntev. Perpendicular kab hla ib leeg ntawm txoj cai kaum.
Ua raws li qhov no hauv kev txiav txim siab, kev sib raug zoo ntawm cov kab sib luag thiab kab perpendicular yog dab tsi?
Parallel kab muaj tib txoj kab nqes thiab yuav tsis sib tshuam. Parallel kab txuas ntxiv, lus, mus ib txhis tsis kov (xav tias cov no kab nyob rau tib lub dav hlau). Ntawm qhov tod tes, txoj kab nqes ntawm kab perpendicular yog cov tsis zoo reciprocals ntawm ib leeg, thiab ib khub ntawm no kab sib tshuam ntawm 90 degrees.
Qhov piv txwv perpendicular yog dab tsi?
Perpendicular - Txhais nrog Piv txwv Ob kab sib txawv ntawm ib leeg ntawm 90 ° lossis lub kaum sab xis yog hu ua perpendicular kab. Piv txwv : AB is perpendicular rau XY vim AB thiab XY sib tshuam ntawm 90 °. Tsis- Piv txwv : Ob kab yog sib npaug thiab tsis sib tshuam.
Pom zoo:
Dab tsi yog qhov txawv ntawm kab rau kab voltage thiab kab rau nruab nrab voltage?
Qhov voltage ntawm ob kab (piv txwv li 'L1' thiab 'L2') yog hu ua kab rau kab (los yog theem rau theem) voltage. Qhov voltage hla txhua qhov winding (piv txwv li ntawm 'L1' thiab 'N' yog hu ua kab rau nruab nrab (lossis theem voltage)
Qhov txawv ntawm perpendicular thiab parallel yog dab tsi?
Parallel kab muaj tib txoj kab nqes thiab yuav tsis sib tshuam. Cov kab sib txuas txuas ntxiv, qhov tseeb, mus ib txhis yam tsis tau kov (piv txwv tias cov kab no nyob rau tib lub dav hlau). Ntawm qhov tod tes, txoj kab nqes ntawm kab perpendicular yog qhov tsis zoo ntawm ib leeg, thiab ib khub ntawm cov kab no sib tshuam ntawm 90 degrees
Dab tsi yog parallel intersecting thiab perpendicular kab?
Dab tsi yog parallel intersecting thiab perpendicular kab? A. Parallel kab yog kab nyob rau hauv ib lub dav hlau uas ib txwm sib nrug deb. Perpendicular kab yog cov kab uas sib tshuam ntawm txoj cai (90 degrees) lub kaum sab xis
Yuav ua li cas koj nrhiav tau txoj kab nqes ntawm ib tug parallel thiab perpendicular kab?
Txhawm rau nrhiav txoj kab nqes ntawm txoj kab no peb yuav tsum tau txais txoj kab rau hauv txoj kab nqes-intercept daim ntawv (y = mx + b), uas txhais tau tias peb yuav tsum tau daws rau y: Qhov nqes hav ntawm kab 4x - 5y = 12 yog m = 4 / 5. Yog li ntawd, txoj kab nqes ntawm txhua kab uas tig mus rau kab no yuav tsum yog m = 4/5. Ob kab yog perpendicular yog tias
Dab tsi yog parallel thiab perpendicular?
Parallel kab yog cov kab hauv ib lub dav hlau uas ib txwm nyob sib nrug deb. Parallel kab yeej tsis sib tshuam. Perpendicular kab yog cov kab uas sib tshuam ntawm txoj cai (90 degrees) lub kaum sab xis
