USAJMO 2021 Problem 4
- Day 2
Carina has three pins, labeled , and , respectively, located at the origin of the coordinate plane. In a move, Carina may move a pin to an adjacent lattice point at distance away. What is the least number of moves that Carina can make in order for triangle to have area 2021?
(A lattice point is a point in the coordinate plane where and are both integers, not necessarily positive.)
