Rotations, reflections, thiab txhais lus yog isometric. Qhov ntawd txhais tau tias cov kev hloov pauv no ua tsis hloov qhov loj ntawm lub daim duab . Yog qhov loj thiab cov duab ntawm lub daim duab yog tsis hloov, ces tus cov duab yog kev sib haum xeeb.
Nyob rau hauv tas li ntawd, ib tug dilation puas ib txwm tsim ib tug congruent daim duab?
A) dilation . Piav: To tsim ib daim duab congruent , lub kaum sab xis ntsuas ntawm daim duab thiab sab ntev ntawm daim duab yuav tsum yog tib yam li lub kaum sab xis ntsuas thiab sab ntev ntawm daim duab ua ntej. Qhov no txhais tau tias peb tsis tuaj yeem txo qis, nthuav dav, lossis cog lus rau daim duab ; los ntawm txhais cov kev hloov pauv hloov qhov loj.
Tsis tas li ntawd, dab tsi yog congruent figures? Ob polygons yog kev sib haum xeeb yog tias lawv yog tib qhov loj thiab cov duab - uas yog, yog tias lawv cov kaum sab xis thiab sab sib npaug. Txav koj tus cursor nas hla qhov chaw ntawm txhua qhov daim duab sab laug kom pom qhov sib thooj ntawm cov sib fim ntawm sab xis.
Tib neeg kuj nug, koj yuav txiav txim siab li cas yog tias ob daim duab sib koom ua ke siv kev hloov pauv?
Piav koj lub laj thawj. Yog koj muaj ob daim duab sib dhos , koj ua tau txiav txim tus kev hloov pauv , los yog series kev hloov pauv , maps ib daim duab mus rau lwm qhov los ntawm kev txheeb xyuas qhov taw qhia lossis qhov txheeb ze ntawm qhov cov duab . Daim ntawv ceeb toom cov ntu tab tom ntsib tib txoj kev.
Cov kev xav puas sib haum xeeb?
Reflected triangles tuaj yeem ua tau kev sib haum xeeb Ua kev sib haum xeeb ob daim duab peb sab yuav tsum yog tib yam duab thiab loj. Txawm li cas los xij, ib daim duab peb sab tuaj yeem cuam tshuam, uas yog, tig mus rau lwm qhov. Tsuav lawv tsis zoo ib yam, daim duab peb sab tseem kev sib haum xeeb.
Pom zoo:
Nws txhais li cas thaum kev sib raug zoo ntawm kev sib raug zoo ua kev cuam tshuam?
Kev sib raug zoo ntawm ob tus neeg uas txhua tus neeg nyob ntawm thiab tau txais kev txhawb zog, txawm tias muaj txiaj ntsig lossis kev puas tsuaj, los ntawm lwm tus. ib qho kev sib cuam tshuam lossis kev sib raug zoo ntawm ob tus neeg, pab pawg, thiab lwm yam
Puas yog ob txoj kab sib luag zoo sib xws lossis tsis sib xws?
Yog tias ob qhov sib npaug piav txog kab sib luag, thiab yog li cov kab uas tsis sib tshuam, qhov system yog ywj siab thiab tsis sib haum. Yog hais tias ob qhov sib npaug piav txog tib kab, thiab yog li cov kab uas hla tus lej tsis kawg, lub kaw lus yog nyob ntawm thiab sib xws
Koj tuaj yeem ua pov thawj li cas 2 daim duab peb sab zoo sib xws siv lub kaum sab xis sab SAS zoo sib xws postulate?
SAS Similarity Theorem hais tias yog ob sab hauv ib daim duab peb sab yog proportional rau ob sab hauv lwm daim duab peb sab thiab lub kaum sab xis nyob rau hauv ob qho tib si congruent, ces ob daim duab peb sab zoo ib yam. Ib qho kev hloov pauv zoo sib xws yog ib lossis ntau qhov kev hloov pauv tsis tu ncua ua raws li kev dilation
Dab tsi yog qhov zoo sib xws ntawm kev sau thiab kev txhais lus?
Kev hloov pauv yog kev sib txuas ntawm RNA los ntawm DNA qauv uas cov cai hauv DNA tau hloov mus rau hauv RNA code ntxiv. Kev txhais lus yog kev sib txuas ntawm cov protein los ntawm mRNA template qhov twg cov cai hauv mRNA hloov mus rau hauv cov amino acid sequence hauv cov protein
Puas yog cov ntsiab lus uas muaj cov tshuaj lom neeg zoo sib xws yuav pom nyob rau tib lub sijhawm lossis hauv tib pab pawg piav qhia koj cov lus teb?
Qhov no yog vim hais tias cov tshuaj muaj zog nyob ntawm tsis muaj valence electrons. Raws li nyob rau hauv ib pawg tag nrho cov ntsiab lus muaj tib yam tsis muaj valence electron uas yog vim li cas lawv muaj cov tshuaj zoo sib xws tab sis nyob rau hauv ib lub sij hawm tsis muaj valence electron sib txawv uas yog vim li cas lawv txawv nyob rau hauv chemical zog
