Cov ntsiab lus uas nyob ntawm tib kab yog hu ua collinear. Lub theorem yog ib nqe lus lej uas tuaj yeem ua pov thawj. Qhov nruab nrab ntawm ib ntu yog taw tes uas faib ntu ua ob ntu sib koom ua ke. Ib qho taw tes (lossis ntu, kab hluav taws xob lossis kab) uas faib ib ntu ua ob ntu sib txuas ua ke faib ntu.
Puas yog midpoint ib ntu ntu?
Ib ntu bisector yog taw tes, kab hluav taws xob, kab, kab ntu, lossis dav hlau uas cuam tshuam cov ntu ntawm nws qhov nruab nrab. Lub midpoint lossis ib ntu bisector bisects ib ntu.
Lub midpoint ua li cas rau ib ntu?
Nyob hauv geometry, qhov nruab nrab yog nruab nrab ntawm kab ntu. Nws yog qhov sib npaug ntawm ob qho kawg, thiab nws yog qhov nruab nrab ntawm ob ntu thiab ntawm qhov kawg. Nws bisects ntu.
Puas yog nruab nrab taw qhia ib kab?
Bisectors yog cov kab uas txiav yam zoo ib nrab, uas txhais tau hais tias lawv mus txog qhov nruab nrab ntawm cov kab. Ua tib zoo saib ntawm daim duab hauv qab no, tsuav yog cov kab dhau los ntawm qhov nruab nrab, lawv yog bisectors! Muaj ntau infinitely bisectors rau ib kab AB.
Puas yog qhov nruab nrab ntawm lub kaum sab xis?
Txoj kab raws li lub hauv paus ntawm nws qhov nruab nrab, Cov kab ntu yog nyob rau ntawm lub hauv paus. Cov kab ntu bisects lub kaum sab xis.
