The only geometry problem in the IMO exam proposed by Vietnam
The IMO 2025 exam consists of 6 problems: 2 arithmetic problems, 2 combinatorial problems, 1 geometry problem and 1 algebra problem (with combinatorial statements and combinatorial thinking requirements). This shows the trend of this year's exam focusing on combinatorial content.
Notably, the only geometry problem in the exam, problem number 2, was proposed by Vietnam and the author was Mr. Tran Quang Hung, a teacher at the High School for the Gifted in Natural Sciences, University of Natural Sciences (Vietnam National University, Hanoi).
This is the fourth time Vietnam has had a problem selected for the official IMO exam, after 1977 (author: Phan Duc Chinh), 1982 (author: Van Nhu Cuong) and 1987 (author: Nguyen Minh Duc).
The 66th International Mathematical Olympiad was held from July 10 to 20 in Sunshine Coast, Queensland, Australia, with the participation of more than 639 contestants from 113 delegations representing countries and territories. This is the second time Australia has hosted the IMO, after the first time in 1988.
The total number of medals in this year's competition includes: 72 gold medals, 104 silver medals and 145 bronze medals.
