Dav hlau thiab peb-sab
Qhov ntxov tshaj plaws geometry yog dav hlau geometry. Lub dav hlau geometry yog kawm txog cov qauv duab thiab ntsuas cov khoom siv (thaj chaw, qhov ntev, lub kaum ntse ntse) ntawm cov kab ncaj thiab plaub txoj kab nkhaus (qhov ntawd yog ntu conic, uas yog ellipses, hyperbolas, thiab parabolas) ntawm lub dav hlau. Lub dav hlau geometry txais txoj kev axiomatic txoj kev, uas yog qhov tseem ceeb hauv keeb kwm ntawm kev xav ntawm kev ua lej.
Cov ntsiab lus ntawm dav hlau geometry kuj ib txwm hloov mus rau cov khoom hauv geometry ntawm peb qhov ntev. Txhawm rau suav lub ntim thiab thaj tsam, cov tib neeg tau pib koom nrog lub tswv yim qub ntawm kev suav.
Tom qab Descartes qhia kev sib koom ua ke, kev sib raug zoo ntawm algebra thiab geometry tau pom tseeb dua thiab ze dua. Qhov no kom qhov kev tsim ntawm kev tsom xam geometry. Kev tsom xam geometry tau tsim los ntawm nws tus kheej los ntawm Descartes thiab Fermat. Nov yog ib qhov chaw tshwm sim tshiab. Los ntawm qhov pom ntawm qhov ntsuas cov ntsuas geometry, cov yam ntxwv ntawm cov duab geometric tuaj yeem raug ntaus nqi rau cov kev ntsuas thiab cov ntsiab lus ntawm cov lej sib npaug ntawm kev sib npaug. Qhov teeb meem ntawm kev faib tawm ntawm cov duab geometric (piv txwv li, faib cov conic hauv peb pawg) tau hloov pauv mus ua teeb meem kev faib tawm ntawm cov lej algebraic ntawm kev sib npaug, uas yog, teeb meem ntawm nrhiav algebraic invariants.
