Cov ntu sib txuas yog yooj yim kab ntu uas sib npaug ntawm qhov ntev. Congruent txhais tias sib npaug. Kev sib haum xeeb kab ntu feem ntau yog qhia los ntawm kev kos tib tus nqi me me tic kab nyob rau hauv nruab nrab ntawm cov ntu, perpendicular mus rau ntu. Peb qhia ib kab los ntawm kos ib kab hla nws ob qhov kawg.

Ntawm no, dab tsi yog ib txoj kab sib txuas?

Kab ntu yog kev sib haum xeeb yog tias lawv muaj qhov ntev. Txawm li cas los xij, lawv yuav tsum tsis txhob sib npaug. Lawv tuaj yeem nyob ntawm txhua lub kaum sab xis lossis kev taw qhia ntawm lub dav hlau. Hauv daim duab saum toj no, muaj ob congruent kab segments.

Tsis tas li ntawd, dab tsi faib ib ntu rau hauv ob ntu sib txuas? Bisector ntawm a kab ntu yog ib qho kab (los yog subset ntawm a kab ) uas cuam tshuam cov ntu ntawm nws qhov nruab nrab. Alternate definition: Bisector ntawm a kab ntu yog ib qho kab (los yog subset ntawm a kab ) uas faib tus segment nyob rau hauv ob congruent segments . Complementary ces kaum yog ob ces kaum tus lej ntawm nws qhov ntsuas yog 90º.

Ua kom pom qhov no, puas tuaj yeem muab faib ua ob ntu sib txuas?

Cov seem yog ntu uas muaj qhov ntev. Cov ntsiab lus uas nyob ntawm tib kab yog hu ua collinear. Qhov nruab nrab ntawm a ntu yog qhov point ntawd faib tus segment nyob rau hauv ob congruent segments . Ib point (or ntu , ray los yog kab) tias faib ib segment rau hauv ob qho tib si ntu bisect ua ntu.

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.
