Ua ntej, yog tias a kev hloov pauv sib tshuam ob kab yog li ntawd cov ces kaum sib raug yog congruent, ces tus kab yog parallel . Thib ob, yog tias a kev hloov pauv sib tshuam ob kab yog li ntawd sab hauv cov ces kaum ntawm tib sab ntawm lub transversal yog supplementary, ces cov kab yog parallel.

Ntxiv mus, dab tsi yog transversal ntawm parallel kab?

Parallel Kab & Kev sib hloov . A kev hloov pauv yog a kab , los yog kab ntu, uas cuam tshuam ob lossis ntau dua lwm yam kab , los yog kab ntu. Thaum a kev hloov pauv kev sib tshuam kab sib npaug , ntau lub ces kaum yog congruent.

Ib tug kuj yuav nug, dab tsi yog transversal kab thiab kaum? Hloov pauv . Lus txhais: A kab uas txiav hla ob lossis ntau dua (feem ntau yog sib npaug) kab . Hauv daim duab hauv qab no, lub kab AB is a kev hloov pauv . Nws txiav hla lub parallel kab PQ thiab RS. Yog nws hla lub parallel kab ntawm txoj cai lub kaum sab xis nws yog hu ua perpendicular kev hloov pauv.

Nyob rau hauv txoj kev no, dab tsi yog cov npe ntawm cov ces kaum ntawm cov kab sib txuas?

Hauv txhua qhov kab sib npaug nyob sib ze lub kaum sab xis yog supplementary. Cov lub kaum sab xis muaj tshwj xeeb npe txheeb xyuas lawv txoj haujlwm nrog kev hwm rau kab sib npaug thiab transversal. Lawv sib xws lub kaum sab xis , hloov sab hauv lub kaum sab xis , los yog alternate sab nrauv lub kaum sab xis . Ib lub kaum sab xis yog congruent rau nws matched lub kaum sab xis.

Puas yog cov kab sib txuas sib txuas?

Yog ob kab sib npaug yog txiav los ntawm ib tug transversal, cov ces kaum sib raug kev sib haum xeeb . Yog ob kab yog txiav los ntawm ib tug transversal thiab cov ces kaum sib raug kev sib haum xeeb , cov kab yog parallel . Sab hauv Angles ntawm Tib Sab ntawm Transversal: Lub npe yog ib qho kev piav qhia ntawm "qhov chaw" ntawm cov ces kaum no.
