Yog ob kab yog txiav los ntawm ib tug transversal thiab alternate sab hauv cov ces kaum yog congruent, ces cov kab yog parallel . Yog ob kab yog txiav los ntawm ib tug transversal thiab tib-sab sab hauv cov ces kaum yog supplementary, ces cov kab yog parallel.

Kev sib raug zoo, lub theorem twg yog qhov tseeb vim li cas cov kab m thiab n yog sib npaug?

Cia m thiab n yog ob kab thiab cov kab raug txiav los ntawm transversal k. Tom qab ntawd, yog tias peb pom tias qhov sib txawv sab hauv cov ces kaum sib npaug, ces m thiab n ua thaum uas tig mus rau ib leeg. Yog li ntawd, lub converse ntawm alternate interiors theorem kom raug justifies tias cov kab yog thaum uas tig mus thaum txiav los ntawm transversal.

Tsis tas li ntawd, qhov twg yuav tsum sib npaug 92 los ua pov thawj tias RS? Angles w and z yuav tsum sib npaug 92 ° rau ua pov thawj tas r s. Qhov no yog vim lub kaum sab xis w sib raug rau lub kaum sab xis muab, thaum lub kaum z yog vertically opposite lub kaum sab xis muab.

Ib yam li ntawd, koj ua pov thawj cov kab sib npaug li cas?

Thawj yog yog tias cov ces kaum sib raug, cov ces kaum uas nyob rau tib lub ces kaum ntawm txhua qhov kev sib tshuam, sib npaug, ces cov kab yog parallel . Qhov thib ob yog yog tias cov ces kaum sab hauv, cov ces kaum uas nyob rau sab nraud ntawm lub transversal thiab sab hauv. kab sib npaug , yog sib npaug, ces tus kab yog parallel.

Cov kab twg yog qhov sib npaug ua rau koj cov lus teb kab P thiab Q?

kab p i q yog thaum uas tig mus vim tib sab sab hauv cov ces kaum yog congruent. kab p i q yog thaum uas tig mus vim qhov sib txawv sab nrauv sab nrauv yog congruent Kab l i m yog thaum uas tig mus vim tib sab sab hauv cov ces kaum yog supplementary Kab l i m yog thaum uas tig mus vim lwm cov ces kaum sab hauv yog supplementary.
