Thawj yog yog tias cov ces kaum sib thooj, cov ces kaum uas nyob rau tib lub ces kaum ntawm txhua qhov kev sib tshuam, sib npaug, ces cov kab yog thaum uas tig mus . Qhov thib ob yog yog tias cov ces kaum sab hauv, cov ces kaum uas nyob rau sab nraud sab ntawm transversal thiab sab hauv kab sib npaug , yog sib npaug, ces tus kab yog thaum uas tig mus.
Ntawm no, koj kos cov kab sib dhos li cas?
Parallel kab yog cim nrog "feathers". Daim ntawv ceeb toom yuav ua li cas lawv tshwm raws li teev: lub kab nrog ib tug plaub yog parallels, thiab cov kab nrog ob tug plaub yog thaum uas tig mus . Ib qho "box" ntawm qhov kev sib tshuam qhia qhov kab yog perpendicular.
Ib yam li ntawd, cov kab sib npaug li cas? Ob kab yog thaum uas tig mus yog tias lawv muaj tib txoj kab nqes, lossis yog tias lawv yog ntsug. Yog ob kab sib npaug tsim ib qho system, tsis muaj kev daws teeb meem rau qhov system. Yog kab kev sib tshuam, cov kab hla hauv ib kis. Lub kaum sab xis ntawm ob kab sib tshuam ua tau txawv.
Ntxiv mus, koj yuav ua li cas qhia tias ob kab yog sib npaug hauv ib qho kev sib npaug?
Peb tuaj yeem txiav txim siab los ntawm lawv kev sib npaug seb ob kab yog parallel los ntawm kev sib piv lawv txoj kab nqes. Yog hais tias cov slopes yog tib yam thiab cov y-intercepts txawv, cov kab yog parallel . Yog hais tias cov slopes txawv, lub kab tsis yog thaum uas tig mus . Tsis zoo li kab sib npaug , kab perpendicular ua kev sib tshuam.
Lub cim rau parallel yog dab tsi?
Ob kab, ob qho tib si hauv tib lub dav hlau, uas tsis muaj kev sib tshuam yog hu ua thaum uas tig mus kab. Parallel kab nyob sib nrug deb ntawm txhua lub sijhawm. Cov cim // yog siv los qhia thaum uas tig mus kab.

Yuav ua li cas koj nthuav qhia cov txheeb cais nyob rau hauv ib daim ntawv qhia?
Cov txiaj ntsig piav qhia suav nrog ib lub rooj nrog cov ntaub ntawv txheeb xyuas tsim nyog xws li. qhov nruab nrab, hom, nruab nrab, thiab tus qauv sib txawv. Cov ntaub ntawv piav qhia yuav tsum muaj feem xyuam rau lub hom phiaj ntawm kev kawm; nws yuav tsum tsis txhob suav nrog rau lub hom phiaj ntawm nws. Yog tias koj tsis mus siv hom nyob qhov twg, tsis txhob suav nrog nws
Yuav ua li cas koj nrhiav tau qhov sib npaug ntawm ib kab uas muab ib tug point thiab ib tug parallel kab?
Qhov sib npaug ntawm kab hauv daim ntawv nqes hav-intercept yog y = 2x + 5. Qhov nqes hav ntawm parallelline yog tib yam: m = 2. Yog li, qhov sib npaug ntawm kab sib npaug yog y = 2x + a. Txhawm rau nrhiav ib qho, peb siv qhov tseeb tias kab yuav tsum dhau los ntawm qhov muab: 5 = (2) ⋅ (− 3) + a
Yuav ua li cas koj parallel kab txiav los ntawm ib tug transversal?
Yog tias ob txoj kab sib txuas raug txiav los ntawm kev hloov pauv, cov ces kaum sab hauv ntawm tib sab ntawm lub transversal yog ntxiv. Yog hais tias ob kab yog txiav los ntawm ib tug transversal thiab cov ces kaum sab hauv ntawm tib sab ntawm lub transversal yog supplementary, cov kab yog parallel
Yuav ua li cas muaj pes tsawg tus tooj liab atoms koj yuav tsum tau kab ntawm ib sab los tsim ib kab 1'm ntev?
Los ntawm kev sib piv, lub ntiaj teb cov pej xeem tsuas yog hais txog 7? 109 neeg. Yog tias koj tuaj yeem ua kab 100,000,000 tooj liab atoms ib sab, lawv yuav tsim ib txoj kab ntev li 1 cm
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
