Kab ntu yog congruent 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. Nyob rau hauv daim duab saum toj no, muaj ob congruent kab ntu.
Nyob rau hauv no, dab tsi yog congruent segments?
Cov seem tsuas yog kab ntu uas sib npaug ntawm qhov ntev. Kev sib haum xeeb txhais tias sib npaug. Kev sib haum xeeb kab ntu feem ntau yog qhia los ntawm kev kos tib tus nqi ntawm cov kab me me hauv nruab nrab ntawm cov ntu , perpendicular rau lub ntu.
Kuj Paub, cov kab sib dhos puas sib haum? 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.
Tsis tas li ntawd, dab tsi yog 2 qhov sib xyaw ua ke?
Kev sib haum xeeb kab ntu yog kab ntu nrog tib qhov ntev. Hauv ib kab ntu , muaj ib lub ntsiab lus uas yuav bisect kab ntu ua ob kev sib haum xeeb kab ntu.
Lub cim rau perpendicular yog dab tsi?
Ob kab uas sib tshuam thiab tsim cov kaum sab xis yog hu ua perpendicular kab. Cov cim ⊥ yog siv los qhia perpendicular kab. Hauv daim duab, kab l ⊥ kab m.

Cov pab pawg twg ntawm cov ntawv teev sijhawm twg yog cov tshuaj chlorine?
Chlorine belongs rau pab pawg neeg ntawm halogens - ntsev tsim - ua ke nrog fluorine (F), bromine (Br), iodine (I) thiab astatine (At). Lawv tag nrho nyob rau hauv kab thib ob los ntawm sab xis ntawm lub rooj sib tham hauv Pawg 17. Lawv cov teeb tsa hluav taws xob zoo sib xws, muaj xya lub tshuab hluav taws xob hauv lawv lub plhaub sab nraud
Txoj kev faib cov ntaub ntawv twg muab cov ntaub ntawv sib npaug ntawm cov ntaub ntawv lossis cov kev tshuaj xyuas hauv txhua chav kawm cov ntaub ntawv?
Quantile. txhua chav kawm muaj cov yam ntxwv sib npaug. Ib qho kev faib tawm ntau yog zoo haum rau cov ntaub ntawv faib tawm. Quantile muab tib tus lej ntawm cov ntaub ntawv muaj nuj nqis rau txhua chav kawm
Yog vim li cas sodium poov tshuaj twj tso kua mis suav hais tias yog ib qho kev thauj mus los uas cov kev taw qhia yog cov sodium thiab poov tshuaj tau pumped?
Sodium-Potassium Pump. Kev thauj mus los yog lub zog xav tau cov txheej txheem ntawm kev siv cov molecules thiab ions hla daim nyias nyias 'nce toj' - tiv thaiv kev sib tw gradient. Txhawm rau txav cov molecules tawm tsam lawv cov concentration gradient, yuav tsum muaj cov khoom siv protein
Cov yam ntxwv twg ntawm cov hlau atoms pab piav qhia vim li cas valence electrons hauv cov hlau yog delocalized?
Ib daim ntawv cog lus hlau yog kev sib koom ntawm ntau cov khoom siv hluav taws xob sib cais ntawm ntau cov ions zoo, qhov twg cov electrons ua raws li 'cov kua nplaum' muab cov khoom tsim nyog. Nws tsis zoo li covalent lossis ionic bonding. Cov hlau muaj zog ionization tsawg. Yog li ntawd, valence electrons tuaj yeem raug delocalized thoob plaws hauv cov hlau
Yuav ua li cas koj paub yog hais tias ib ntu yog congruent?
Cov ntu sib txuas yog cov kab kab uas sib npaug ntawm qhov ntev. Congruent txhais tias sib npaug. Cov kab sib txuas feem ntau yog qhia los ntawm kev kos tib tus nqi ntawm cov kab me me nyob rau hauv nruab nrab ntawm cov ntu, nyob rau ntawm ntu. Peb qhia ib kab los ntawm kos ib kab hla nws ob qhov kawg
