Yog ib khub ntawm opposite sab ntawm a quadrilateral yog thaum uas tig mus thiab congruent, ces lub quadrilateral yog a parallelogram. Yog ob leeg khub ntawm opposite ces kaum ntawm a quadrilateral yog congruent, ces lub quadrilateral yog a parallelogram.
Ib yam li ntawd, tib neeg nug, cov duab zoo li cas muaj ib khub ntawm qhov sib luag?
trapezoids
Tom qab, lo lus nug yog, dab tsi yog qhov sib npaug sab? Kev txhais ntawm Parallel Ob sab los yog kab thaum uas tig mus yog tias lawv yog cov kab uas ib txwm nyob deb ntawm ib leeg thiab yuav tsis sib tshuam lossis kov. Qhov ntawd yog qhov nws txhais tau tias yog thaum uas tig mus.
Hais txog qhov no, dab tsi muaj tsawg kawg yog ib khub ntawm qhov sib npaug?
A trapezoid muaj tsawg kawg yog ib khub ntawm parallel sab . Nws yuav muaj ob! Koj tuaj yeem yooj yim nrhiav lwm cov ntsiab lus rau a trapezoid uas qhia nws tsuas yog muaj ib tug khub ntawm parallel sab.
Puas yog trapezium muaj qhov sib luag?
A trapezium yog txhais los ntawm cov khoom nws ua tsis yog muaj . Nws muaj tsis muaj parallel sab . Yog quadrilateral muaj ib par parallel sab , nws yuav yog ib tug trapezoid. Yog ob khub ntawm sab yog parallel , nws yuav yog parallelogram.

Vim li cas kev taw qhia ntawm cov kab hlau nplaum yog los ntawm sab qaum teb mus rau sab qab teb?
Thaum nws los txog rau hlau nplaum, opposites nyiam. Qhov tseeb no txhais tau hais tias sab qaum teb kawg ntawm cov hlau nplaum nyob rau hauv ib lub compass yog attracted rau sab qab teb magnetic ncej, uas nyob ze rau thaj tsam qaum teb ncej. Cov kab hlau nplaum sab nraud ntawm cov hlau nplaum ruaj khov ib txwm khiav ntawm sab qaum teb sib nqus ncej mus rau sab qab teb magnetic ncej
Koj ua pov thawj li cas ntawm cov ces kaum sab nrauv ntawm daim duab peb sab yog 360?
Lub kaum sab nrauv ntawm daim duab peb sab yog sib npaug rau qhov sib npaug ntawm cov kaum sab hauv sab nraud. Yog xav paub ntxiv txog qhov no saib Daim duab peb sab sab nraud lub kaum sab xis theorem. Yog tias lub kaum sib npaug raug coj los ntawm txhua qhov vertex, cov ces kaum sab nrauv ib txwm ntxiv rau 360 ° Qhov tseeb, qhov no muaj tseeb rau txhua qhov convex polygon, tsis yog daim duab peb sab
Vim li cas nws thiaj li hais tias lub Orthocenter ntawm daim duab peb sab obtuse yuav tsum nyob rau sab nraud ntawm daim duab peb sab?
Nws hloov tawm tias tag nrho peb qhov siab ib txwm sib tshuam ntawm tib lub ntsiab lus - lub npe hu ua orthocenter ntawm daim duab peb sab. Lub orthocenter tsis yog ib txwm nyob hauv daim duab peb sab. Yog tias daim duab peb sab yog obtuse, nws yuav nyob sab nraud. Txhawm rau ua kom qhov no tshwm sim cov kab qhov siab yuav tsum tau txuas ntxiv kom lawv hla
Dab tsi yog qhov flux los ntawm lub voos xwmfab ntawm sab yog tias tus nqi ntawm Q yog ntawm ib qho ntawm nws lub ces kaum?
Raws li peb paub tias, tag nrho cov flux los ntawm tus nqi q yog q / ε 0 (Gauss txoj cai). Yog hais tias tus nqi yog nyob rau ntawm lub ces kaum ntawm lub voos xwmfab, ib co ntawm cov flux nkag mus rau hauv lub voos xwmfab thiab tawm los ntawm ib co ntawm nws lub ntsej muag. Tab sis qee qhov flux tsis nkag mus rau hauv lub voos xwmfab. Qhov 1/8th no yuav muab faib ua 3 ntu dua
Dab tsi yog kev sib raug zoo ntawm sab nrauv thiab sab hauv lub kaum sab xis ntawm daim duab peb sab?
Cov kaum sab hauv yog hu ua Sab hauv cov ces kaum. Cov lej ntawm cov kaum sab hauv ntawm daim duab peb sab yog ib txwm 180 degrees. Lub kaum sab nrauv yog lub kaum sab xis ntawm ib sab ntawm ib qho duab, thiab ib txoj kab txuas ntxiv los ntawm sab tom ntej. Qhov sib npaug ntawm lub kaum sab nrauv thiab nws lub kaum sab hauv uas nyob ib sab kuj yog 180 degrees
