  1. Cum pot simplifica vectorii geometria plana ?In aceasta publicatie vom prezenta rezultatele investigatiei noastre privind tema ‘‘Coliniaritate vectoriala’’ , ca parte din unitatea de invatare “Calcul vectorial in geometria plana’’

  2. Diana + Ionela + Roxana + Oana Liceul Teoretic Nicolae Cartojan cls a IX a Giurgiu

  3. Trei aspecte vom supune atentiei voastre : 1 . Consideratii teoretice 2 . Aplicatiile rezolvate 3 . Analiza rezultatelor si concluzii

  4. Consideratii teoretice : conditii vectoriale de coliniaritate

  5. Aplicatiile rezolvate : 1.relatia vectoriala intre O,G,H .

  6. 2.teorema Menelaus

  7. 3.coliniaritatea mijloacelor celor trei diagonale ale unui patrulater complet .

  8. Analiza rezultatelor si concluzii : Abordarea metodei vectoriale pentru rezolvarea unor probleme cu nivel destul de ridicat de geometrie plana privind tema paralelismului , concurentei , coliniaritatii scoate in evidenta rationamentul acestei metode : claritate , simplitate , eleganta , profunzime .
