Rau ob qho tib si polygons nrog tib tus naj npawb ntawm sab: Lawv ib txwm zoo sib xws . Vim lawv muaj ob sab tag nrho tib qhov ntev lawv yuav tsum nyob rau tib lub proportions, thiab lawv cov ces kaum sab hauv yeej ib txwm zoo ib yam, thiab yog li ntawd ib txwm zoo sib xws.
Kuj paub yog, cov polygons zoo sib xws?
Cov peev txheej. zoo sib xws polygons Ob polygons nrog tib lub cev, tab sis tsis yog tib qhov loj. Cov ces kaum sib thooj ntawm zoo sib xws polygons yog congruent (raws li qhov qub) thiab cov sab sib txuas yog proportional (hauv tib qhov piv). CongruentCongruent cov duab zoo ib yam ntawm qhov loj, zoo thiab ntsuas.
Kuj Paub, nws txhais li cas rau 2 polygons zoo sib xws? Polygons . Ib ob polygons zoo ib yam yog lawv cov ces kaum sib thooj yog congruent thiab kev ntsuas ntawm lawv cov sib raug zoo sab yog proportional: Nyob rau hauv daim duab saum toj no tus piv los yog qhov ntsuas qhov ntsuas ntawm lub quadrilateral mus rau sab laug piv rau lub quadrilateral rau sab xis yog ½.
Yog li ntawd, tag nrho cov polygons zoo sib xws?
Kev sib haum xeeb cov duab muaj tib qhov loj me, tib lub kaum sab xis, tib sab thiab tib cov duab. Lawv yog IDENTICAL! Kev sib haum xeeb cov duab yeej ib txwm zoo sib xws , mas zoo sib xws cov duab feem ntau tsis yog kev sib haum xeeb - Ib qho loj dua thiab ib qho me dua. Hauv kev sib haum xeeb cov duab, qhov sib piv ntawm qhov sib thooj yog 1: 1.
Puas yog daim duab peb sab yog ib qho polygon tsis tu ncua?
A tsis tu ncua polygon yog a polygon qhov twg tag nrho cov sab thiab cov ces kaum yog tib yam. Ib qho kev sib npaug daim duab peb sab yog a tsis tu ncua polygon . Nws muaj tag nrho cov tib sab thiab tib lub kaum sab xis. Ib isosceles daim duab peb sab muaj ob sab sib npaug thiab ob qhov sib npaug.
Pom zoo:
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 4 qhov zoo sib xws uas txhua lub hlwb sib koom?
Txhua lub hlwb muaj cov qauv thiab kev ua haujlwm zoo sib xws. Cov qauv sib koom los ntawm txhua lub hlwb muaj xws li cell membrane, aqueous cytosol, ribosomes, thiab genetic material (DNA). Txhua lub hlwb yog tsim los ntawm tib yam plaub yam ntawm cov organic molecules: carbohydrates, lipids, nucleic acids, thiab cov proteins
Puas yog txhua qhov sib npaug sib npaug sib npaug?
Thawj qhov sib npaug sib npaug yog qhov tseeb yog tias nws muaj kev txuag kom muaj nuj nqis. Piv txwv li, qhov sib npaug sib cais yeej ib txwm muaj tseeb, txij li lub ntsiab lus lawv yog ntawm daim ntawv: M(y) + N(t) = 0, yog li ϕ(t, y) = A(y) + B(t) yog a khaws cia kom muaj nuj nqis
Puas yog tus polygon yog ib daim duab zoo?
Tsis zoo li cov duab dav hlau, cov duab khoom tsis tiaj tus; lawv muaj peb qhov ntev. Qee cov duab khoom muaj qhov nkhaus; lawv tuaj yeem yob. Nco ntsoov tias lub khob hliav qab thiab lub tog raj kheej muaj ob qho tib si nkhaus thiab tiaj tus. Lub ntsej muag ntawm qee cov duab khoom yog polygons
