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.
