In 2014, the “Iran Geometry Olympiad” was launched by a group consisting of activists of the Mathematical Olympiad in Iran. Now, this competition is held annually in four different levels with the participation of students in grades 7-12 and geometry lovers who graduated from schools around the world.
The first edition of IGO was in 2014. The contest date was September 4 (the Birthdate of Abu Reyhan Al-Biruni, an Iranian polymath from the 10th century) in two different levels (elementary and advanced). This event was organized with the support of the Iranian National Mathematical Olympiad Committee in two main cities of Iran, Tehran (the capital) and Isfahan. The Sharif University of Technology in Tehran and the Mathematics House in Isfahan hosted the competition in 2014.
IGO 2015 was the first occurrence of IGO as an international event. In 2015, the organizers decided to promote the exam by increasing the number of Iranian participants and also by inviting other countries to hold the exam. In total, 23 other countries accepted the invitation, and the exam was held on September 3, 2015, with more than 650 students from 24 countries. In Iran, the host of the contest was Sharif University of Technology (Tehran). Also, this year, the structure of the competition has changed from the first year. The competition was held in four levels, including elementary, intermediate, advanced (for students in grades 7-12), and a free level (with no limit on the age and specialized for interested persons who have graduated from school). The exam of each level consisted of 5 problems.
