Cov perpendicular kev hloov pauv theorem hais tias yog muaj ob thaum uas tig mus kab hauv tib lub dav hlau thiab muaj ib txoj kab perpendicular rau ib tug ntawm lawv, ces nws kuj perpendicular mus rau lwm tus. Cia peb xav txog ib khub ntawm thaum uas tig mus kab, l1 thiab l2, thiab kab k uas yog perpendicular rau l1.

Ua raws li qhov no hauv kev txiav txim siab, dab tsi yog qhov yuav tsum tau ua rau lub perpendicular rau parallels theorem siv?

Perpendicular rau Parallels Theorem hais tias nyob rau hauv ib lub dav hlau, yog tias ob kab yog perpendicular mus rau tib kab, ces lawv thaum uas tig mus rau ib leeg. Yog li, cov lus teb zoo tshaj plaws yog: Cov kab yuav tsum pw hauv tib lub dav hlau. Yog cov kab perpendicular mus rau tib lub dav hlau, lawv yog thaum uas tig mus.

Tom qab ntawd, lo lus nug yog, dab tsi yog ib qho kev sib luag thiab kab perpendicular? 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.

Dhau li ntawm no, dab tsi yog piv txwv ntawm kab perpendicular?

Perpendicular kab tshwm sim txhua lub sij hawm ob kab ntsib ntawm lub kaum sab xis 90 °, tseem hu ua lub kaum sab xis. Qee lub sij hawm koj yuav pom me ntsis square nyob rau hauv lub ces kaum ntawm lub kaum sab xis, qhia nws yog perpendicular . Muaj ntau piv txwv ntawm kab perpendicular nyob rau hauv lub neej txhua hnub, nrog rau ib tug football teb thiab tsheb ciav hlau lem.

Koj ua pov thawj perpendicular li cas?

Cov linear khub perpendicular theorem hais tias thaum ob txoj kab ncaj nraim sib tshuam ntawm ib qho taw tes thiab tsim ib khub kab sib npaug, 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, cov kab tau ua pov thawj perpendicular rau ib leeg.
