Abstract:V magistrskem delu se najprej seznanimo s trilinearnimi in baricentričnimi koordinatami. Nato spoznamo izotomično in izogonalno transformacijo. Po uvodnih pojmih je podrobneje opisan problem, ki ga rešujemo postopoma. Začnemo z najenostavnejšimi liki, katerih geometrijo dokaj dobro poznamo. Pri iskanju točke, ki bi bila primerna za postavitev oznake večkotnika, naletimo na ogromno kandidatov, vendar se izkaže, da jih ima večina določene pomanjkljivosti. Po opisanem postopku iskanja primerne točke in nekaj primerih se zopet vrnemo k trikotniku saj določimo algoritem, ki nas za poljubni večkotnik pripelje do točke, kjer moramo poiskati primerno točko ravno v trikotniku. Tu se srečamo s trikotniku včrtanimi elipsami in najbolj značilne tudi opišemo. Posebej obravnavamo tudi Lemoinovo elipso in Spiekerjevo točko, kar je tudi rešitev našega problema.

Title:Where should the label for a polygon be placed?
Abstract:In the following master thesis we first learn about trilinears, barycentrics. Then we describe isotomic and isogonal conjugate. After describing the main problem, we start searching for the most optimal place for placing laber for a polygon. We start with triangle and quadrilateral and we find out, that a lot of possible candidates (points) have some imperfections. According to the procedure described for a suitable point and some examples, we return to the triangle again since we define an algorithm that leads us to conclusion that a point for placing a label for general polygon is a point in triangle which we get as result of algorithm. We consider ellipses inscribed in the triangle and some triangle centres related to these ellipses. At the end we show results related to Lemoine ellipse and Spieker centre, which are closely connected with the final step of the solution to our problem.
Keywords:the centre of a polygon, parallel polygon, Spieker centre, Lemoine ellipse, trilinears, barycentrics, inscribed ellipse, izotomic conjugate, isogonal conjugate, Nagel point, Gergonne point
