Kab Seg . Lub sijhawm kaw sib raug mus rau ib feem ntawm lub infinite kab . Kab ntu feem ntau sau nrog ob tsab ntawv sib raug mus rau lawv qhov kawg, hais thiab, thiab tom qab ntawd sau. Qhov ntev ntawm cov kab ntu yog qhia nrog ib qho overbar, yog li qhov ntev ntawm qhov kab ntu yuav sau.
Kuj tseem paub yog, qhov sib thooj txhais li cas?
Cov khoom sib thooj ntawm Kev sib haum xeeb Cov duab. Lo lus sib raug hais txog ntu uas phim ntawm ob kev sib haum xeeb daim duab peb sab. Koj tuaj yeem txheeb xyuas sib raug kaum thiab sib raug sab . Lawv yuav muaj tib qhov ntev hauv kev sib haum xeeb daim duab peb sab.
Tsis tas li ntawd, ntu bisector hauv geometry yog dab tsi? Kab Ntu Bisector . Txhais: Ib kab, ray los yog ntu uas txiav lwm txoj kab ntu ua ob qhov sib npaug. Sim no Drag ib qho ntawm cov txiv kab ntxwv dots ntawm A lossis B thiab nco ntsoov cov kab AB ib txwm faib cov kab PQ rau ob qhov sib npaug.
Ua li no, qhov sib piv txhais li cas hauv lej?
Thaum ob kab hla los ntawm lwm txoj kab (uas yog hu ua Transversal), cov ces kaum hauv cov ces kaum yog hu ua sib raug lub kaum sab xis. Piv txwv li: a thiab e sib raug lub kaum sab xis. Thaum ob kab sib npaug Sib raug Lub kaum sab xis yog sib npaug.
Nws txhais li cas kom muaj kev sib haum xeeb?
Kev sib haum xeeb . Angles yog kev sib haum xeeb thaum lawv loj tib yam (hauv degrees lossis radians). Sab yog kev sib haum xeeb thaum lawv yog tib qhov ntev.

Yuav daws qhov tsis sib npaug ntawm cov kab sib npaug thiab cov kab sib npaug sib npaug li cas?
Kev daws qhov tsis sib npaug ntawm qhov sib npaug yog zoo ib yam li kev daws cov kab sib npaug. Qhov sib txawv tseem ceeb yog koj tig lub cim tsis sib xws thaum faib lossis muab faib los ntawm tus lej tsis zoo. Graphing linear inequalities muaj ob peb qhov sib txawv ntxiv. Qhov uas yog qhov ntxoov ntxoo muaj xws li qhov tseem ceeb uas qhov kev tsis sib xws ntawm cov kab tawm muaj tseeb
Dab tsi yog qhov sib txawv ntawm qhov sib txawv ntawm cov kab sib txuas thiab ntau qhov sib piv?
6. (2 lub cim) Qhov sib txawv ntawm cov kab sib txuas (kev sib piv) thiab ntau qhov sib piv yog dab tsi? Cov kab sib xyaw ua ke yog npaj sib piv; uas yog, tshwj xeeb txhais tau tias yog ua ke nyob rau hauv ntau txoj kev thiab contrasted nrog rau lwm yam kev sib txuas ntawm txhais tau tias
Puas yog cov kab sib txuas ua pov thawj cov kab sib txuas?
Thawj yog yog tias cov ces kaum sib thooj, cov ces kaum uas nyob rau tib lub ces kaum ntawm txhua qhov kev sib tshuam, yog sib npaug, ces cov kab sib npaug. Qhov thib ob yog yog tias qhov sib txawv sab hauv lub kaum sab xis, cov ces kaum uas nyob rau sab nraud ntawm lub transversal thiab sab hauv cov kab sib npaug, sib npaug, ces cov kab sib npaug
Dab tsi ntawm cov khoom sib txuas sib txuas muaj nyob ntawm cov dej molecules?
Piv txwv li, dej molecules yog tuav ua ke los ntawm hydrogen bonds ntawm hydrogen atom ntawm ib lub molecule thiab cov pa atom ntawm lwm tus (daim duab: hydrogen bonds). Hydrogen bonds yog ib qho muaj zog intermolecular quab yuam thiab muaj zog dua lwm cov dipole-dipole rog
Puas yog cov kab sib txuas sib txuas hauv hyperbolic geometry?
Hauv hyperbolic geometry, muaj ob hom kab sib npaug. Yog hais tias ob kab tsis sib tshuam nrog tus qauv ntawm hyperbolic geometry tab sis lawv sib tshuam ntawm nws tus ciam teb, ces cov kab yog hu ua asymptotically parallel lossis hyperparallel
