Cov nruab nrab ntawm daim duab peb sab yog ib ntu txuas nrog ib qho vertex mus rau qhov nruab nrab ntawm sab nraud. Cov cov neeg nruab nrab ntawm ib daim duab peb sab yog concurrent (lawv sib tshuam hauv ib qho taw tes ). Cov point ntawm concurrency ntawm cov neeg nruab nrab yog hu ua centroid ntawm daim duab peb sab.
Ntxiv mus, dab tsi yog concurrency ntawm medians Theorem?
Concurrence ntawm Medians ntawm ib daim duab peb sab. Cov cov neeg nruab nrab ntawm ib daim duab peb sab yog concurrent thiab lub ntsiab lus ntawm concurrence, lub centroid, yog ib feem peb ntawm qhov kev ncua deb ntawm lub opposite sab mus rau lub vertex raws li qhov nruab nrab.
Ib tug kuj yuav nug, dab tsi yog lub ntsiab lus ntawm concurrency rau qhov siab? Lub orthocenter yog lub point ntawm concurrency ntawm peb qhov siab ntawm ib daim duab peb sab. Yuav kom nkag siab qhov no txhais tau li cas, peb yuav tsum xub txiav txim siab seb qhov twg yog qhov twg qhov siab yog. Ib qhov siab yog ib txoj kab uas hla dhau ntawm lub vertex ntawm ib daim duab peb sab thiab uas yog perpendicular rau kab uas muaj qhov opposite sab ntawm hais vertex.
Dab tsi yog lub ntsiab lus ntawm concurrency rau perpendicular bisectors?
Cov perpendicular bisectors ntawm peb sab ntawm daim duab peb sab yog concurrent hauv a taw tes uas yog equidistant (qhov deb tib yam) los ntawm lub vertices ntawm daim duab peb sab. Cov point ntawm concurrency ntawm perpendicular bisectors yog lub npe hu ua lub circumcenter ntawm daim duab peb sab.
Dab tsi yog hu ua centroid?
A nruab nrab ntawm daim duab peb sab yog lub ntsiab lus uas peb qhov nruab nrab ntawm daim duab peb sab sib ntsib. Qhov nruab nrab ntawm ib daim duab peb sab yog ib txoj kab los ntawm ib qho vertex mus rau nruab nrab taw tes ntawm sab nraud ntawm daim duab peb sab. Cov nruab nrab kuj yog hu ua qhov chaw ntawm lub ntiajteb txawj nqus ntawm daim duab peb sab.
