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"}],"quality_controlled":"1","page":"737-760","department":[{"_id":"HeEd"}],"day":"05","_id":"14464","oa":1,"date_created":"2023-10-29T23:01:18Z","type":"journal_article","date_published":"2023-10-05T00:00:00Z","year":"2023","publication_identifier":{"issn":["0129-0541"],"eissn":["1793-6373"]}}
