This problem was initially posed by Nandakumar [17, 22] and was first studied by Kiss, Pach, and Somlai [13], who showed that if Δ′ is the smallest area isosceles triangle containing Δ, then Δ′ and Δ share a side and an angle. In the present paper, we prove that for any triangle Δ, every maximum area isosceles triangle embedded in Δ and every maximum perimeter isosceles triangle embedded in Δ shares a side and an angle with Δ. Somewhat surprisingly, the case of minimum perimeter enclosing triangles is different: there are infinite families of triangles Δ whose minimum perimeter isosceles containers do not share a side and an angle with Δ.","lang":"eng"}],"type":"journal_article","day":"05","month":"10","article_processing_charge":"No","date_updated":"2023-12-13T13:04:55Z","title":"Optimal embedded and enclosing isosceles triangles","quality_controlled":"1","status":"public","oa_version":"Preprint","oa":1,"date_created":"2023-10-29T23:01:18Z","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","publisher":"World Scientific Publishing","scopus_import":"1"}
