Parallel kab thiab lawv qhov chaw siab tshaj yooj yim. Yog koj pom ib kab nrog qhov zoo txoj kab nqes (yog li nws yog qhov nce kab ), then the kab perpendicular yuav tsum muaj qhov tsis zoo nqes hav (vim nws yuav muaj los ua ib tug txo kab ). Yog li perpendicular kab muaj nqes hav uas muaj opposite kos npe.
Nyob rau hauv no hais txog, puas perpendicular kab muaj opposite slopes?
Tsis muaj teeb meem dab tsi y-intercepts yog , kab yog perpendicular ntev lawv txoj kab nqes rov qab kev sib raug zoo ntawm ib leeg. Cov kab perpendicular muaj qhov sib npaug sib npaug . Ob leeg no cov kab muaj qhov sib npaug mus rau txoj kab nqes ntawm 7 nyob rau hauv thawj kab zauv, tab sis tsuas yog thawj kab yog cov rov qab sib npaug.
Ib tug kuj yuav nug, dab tsi yog qhov tsis zoo reciprocal nqes hav? Kev Sib Tham Sib Tham . Qhov tshwm sim ntawm kev noj cov kev sib raug zoo ntawm tus lej thiab tom qab ntawd hloov lub cim. Piv txwv li, lub kev tsis sib haum xeeb ntawm 5 yog, thiab cov kev tsis sib haum xeeb ntawm yog. Lus Cim: Cov kab perpendicular muaj qhov chaw siab tshaj uas yog tsis zoo reciprocals ntawm ib leeg.
Tom qab ntawd, ib tug kuj yuav nug, nws txhais li cas thaum ib kab yog perpendicular mus rau lwm txoj kab?
A kab yog perpendicular rau lwm tus yog tias nws ntsib lossis hla nws ntawm lub kaum sab xis (90 °). Sim no Drag lub txiv kab ntxwv dot ntawm point A. Tus kab AB will perpendicular rau DF tsuas yog thaum nws ntsib nws ntawm 90 ° Hide. Perpendicular txhais tau tias "ntawm txoj cai kaum".
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.

Yuav daws qhov tsis sib npaug ntawm cov kab sib npaug thiab cov kab sib npaug sib npaug li cas?
Kev daws qhov tsis sib npaug ntawm qhov sib npaug yog zoo ib yam li kev daws cov kab sib npaug. Qhov sib txawv tseem ceeb yog koj tig lub cim tsis sib xws thaum faib lossis muab faib los ntawm tus lej tsis zoo. Graphing linear inequalities muaj ob peb qhov sib txawv ntxiv. Qhov uas yog qhov ntxoov ntxoo muaj xws li qhov tseem ceeb uas qhov kev tsis sib xws ntawm cov kab tawm muaj tseeb
Dab tsi yog qhov sib txawv ntawm qhov sib txawv ntawm cov kab sib txuas thiab ntau qhov sib piv?
6. (2 lub cim) Qhov sib txawv ntawm cov kab sib txuas (kev sib piv) thiab ntau qhov sib piv yog dab tsi? Cov kab sib xyaw ua ke yog npaj sib piv; uas yog, tshwj xeeb txhais tau tias yog ua ke nyob rau hauv ntau txoj kev thiab contrasted nrog rau lwm yam kev sib txuas ntawm txhais tau tias
Puas yog txhua qhov sib npaug sib npaug sib npaug?
Thawj qhov sib npaug sib npaug yog qhov tseeb yog tias nws muaj kev txuag kom muaj nuj nqis. Piv txwv li, qhov sib npaug sib cais yeej ib txwm muaj tseeb, txij li lub ntsiab lus lawv yog ntawm daim ntawv: M(y) + N(t) = 0, yog li ϕ(t, y) = A(y) + B(t) yog a khaws cia kom muaj nuj nqis
Nws puas yuav ua rau pom qhov sib npaug ntawm kab sib npaug mus rau ib kab thiab los ntawm ib qho taw tes ntawm kab?
Qhov sib npaug ntawm ib kab uas yog parallel lossis perpendicular rau ib kab? Cov lus teb tau: Cov nqes hav ntawm cov kab sib npaug sib npaug. Hloov txoj kab nqes paub thiab cov kev sib koom ua ke ntawm ib qho taw tes ntawm lwm txoj kab rau hauv daim ntawv point-slope kom pom qhov sib npaug ntawm kab sib npaug
Dab tsi yog qhov sib txawv ntawm cov kab lus sib npaug thiab qhov sib npaug sib npaug?
Cov kab lus sib npaug muaj qhov muaj txiaj ntsig zoo ib yam tab sis tau nthuav tawm nyob rau hauv ib hom ntawv sib txawv uas siv cov khoom ntawm cov lej xws li ax + bx = (a + b) x yog cov kab lus sib npaug. nruj me ntsis, lawv tsis yog 'sib npaug', yog li peb yuav tsum siv 3 kab sib luag hauv 'sib npaug' es tsis yog 2 raws li qhia ntawm no
