eller <b>evklidsk geometri</b> er eit <a href="/wiki/Matematikk" title="Matematikk">matematisk</a> system tilskriven den greske matematikaren <a href="/wiki/Euklid_av_Alexandria" class="mw-redirect" title="Euklid av Alexandria">Euklid av Alexandria</a>. Boka hans <i><a href="/w/index.php?title=Elementa_av_Euklid&amp;action=edit&amp;redlink=1" class="new" title="Elementa av Euklid (sida finst ikkje)">Elementa</a></i> var den første systematiske diskusjonen rundt <a href="/wiki/Geometri" title="Geometri">geometri</a>. Denne boka har vore ei av dei viktigaste bøkene gjennom historia. Ho var geometrilærebok i den vestlege verda i nærare 2000 år og i desse åra var ikkje euklidsk naudsynt som adjektivt, fordi det fanst ikkje annan geometri. </p><p>Metoden gjekk ut på å godta nokre få <a href="/wiki/Aksiom" title="Aksiom">aksiom</a>, og deretter utgreie fleire <a href="/wiki/Teorem" title="Teorem">teorem</a> frå desse aksioma. Mange av resultat til Euklid hadde alt vorte bevist av greske matematikarar, men Euklid var den første til å vise at desse resultata kunne bli sett i samanheng i eit avansert deduktivt system. </p>
