So, I did G1s. Here are solutions to a few of them. I think they were really INMO level. Not much theory was needed. It's true that almost everything was angle chase-able. Although $2017$ G$1$ was an exception, as it had pappus. But the rest were nice. The hardest would also be $2017$ G$1$. It's not hard-hard, but hard in terms of theoretically. The second hardest would probably be $2018$ G$1.$ Anand had proof with no words. I will add the image here. One should definitely check! Then, the third hardest would probably be $2009$ G$1.$ The right construction was hard for me to guess. Then $2005$ G1. And then $2007$G$1,$ since the right use of similarities were required. Also I, fortunately(?) didn't use any ggb , so I would recommend making your own diagrams. And before starting, I would like to thanks every one of you who comes here almost daily and views this blog! I hope this blog is helpful to you in some way. Yeah, we crossed 6k views! ðŸ’– So here are 5+1 problems,
