INMO 25 Training Camp Geometry problems
This post contains a unique mix of geometry problems with diverse techniques: Angle chasing, power of a point, complex numbers, inversion and Euclidean transformations. The solutions of some of these problems are not available elsewhere in the internet. I believe that since I tried searching a lot before rolling my sleeves and attempting them. I used this set in INMO training camp 2024-25 at Bangalore, Bhopal and Chennai. Enjoy!
