The problem was posed in the year 1891 to Josip Plemelj by his mathematics teacher Vincenc Borštner in secondary school in Ljubljana. Plemelj has solved the problem in an original wayV prispevku obravnavamo nekatere geometrijske konstrukcije trikotnika z dano osnovnico ?$c$?, višino ?$v_c$? nanjo in razliko ?$\alpha - \beta$? kotov ob osnovnici. Nalogo je Josipu Plemlju dal leta 1891 njegov profesor matematike Vincenc Borštner na ljubljanski gimnaziji. Plemelj je nalogo rešil na originalen načinTEXTznanstveno časopisjejournalsSlovenian National E-content AggregatorNational and University Library of SloveniaDruštvo matematikov, fizikov in astronomov
