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."}],"volume":34,"_id":"14464","scopus_import":"1","author":[{"first_name":"Áron","last_name":"Ambrus","full_name":"Ambrus, Áron"},{"last_name":"Csikós","first_name":"Mónika","full_name":"Csikós, Mónika"},{"full_name":"Kiss, Gergely","first_name":"Gergely","last_name":"Kiss"},{"last_name":"Pach","first_name":"János","full_name":"Pach, János","id":"E62E3130-B088-11EA-B919-BF823C25FEA4"},{"full_name":"Somlai, Gábor","last_name":"Somlai","first_name":"Gábor"}],"issue":"7","publication_status":"published","article_processing_charge":"No","department":[{"_id":"HeEd"}],"date_created":"2023-10-29T23:01:18Z","title":"Optimal embedded and enclosing isosceles triangles","intvolume":"        34","page":"737-760","quality_controlled":"1","publisher":"World Scientific Publishing","article_type":"original","date_published":"2023-10-05T00:00:00Z","type":"journal_article","publication_identifier":{"issn":["0129-0541"],"eissn":["1793-6373"]},"oa":1,"main_file_link":[{"url":"https://doi.org/10.48550/arXiv.2205.11637","open_access":"1"}],"status":"public","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","publication":"International Journal of Foundations of Computer Science","oa_version":"Preprint","month":"10","language":[{"iso":"eng"}]}]
