Peb ua tau txiav txim los ntawm lawv equations seb ob kab yog thaum uas tig mus los ntawm kev sib piv lawv txoj kab nqes. Yog cov nqes hav yog tib yam thiab cov y-intercepts txawv, cov kab yog thaum uas tig mus . Yog cov nqes hav txawv, cov kab tsis yog thaum uas tig mus . Tsis zoo li thaum uas tig mus kab, kab perpendicular ua kev sib tshuam.

Cov neeg kuj nug, koj ua pov thawj li cas ib kab yog parallel rau ib qho kev sib npaug?

Ob kab yog parallel yog tias muaj tib txoj kab nqes. Piv txwv 1: Nrhiav txoj kab nqes ntawm lub kab parallel mus rau kab 4x – 5y = 12. Kom nrhiav tau txoj kab nqes ntawm no kab peb yuav tsum tau kab rau hauv nqes hav-intercept daim ntawv (y = mx + b), uas txhais tau tias peb yuav tsum tau daws rau y: Txoj kab nqes ntawm lub kab 4x – 5y = 12 m = 4/5.

Qhov thib ob, 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.

Ntxiv rau qhov no, piv txwv li cov kab sib luag yog dab tsi?

Parallel kab yog ob lossis ntau dua kab uas yeej tsis sib tshuam. Piv txwv ntawm cov kab sib txuas nyob ib ncig ntawm peb, hauv ob sab ntawm nplooj ntawv no thiab hauv rhawv ntawm lub thawv ntawv.

Koj ua pov thawj li cas cov kab yog perpendicular?

Lub linear khub perpendicular theorem hais tias thaum ob ncaj kab intersect ntawm ib tug taw tes thiab tsim ib tug linear khub ntawm vaj huam sib luag kaum, lawv yog perpendicular . Ib khub ntawm cov ces kaum yog xws li cov sum ntawm cov ces kaum yog 180 degrees. Raws li cov ces kaum ntsuas 90 degrees, lub kab muaj pov thawj los ua perpendicular rau ib leeg.
