Yes. You also need O(N) polygon triangulation, Voronoi diagram, Euler's theorem, Delaunay triangulation, Complex numbers in geometry, Convex hull in 3d, Other Euler's theorem, TSP in polynomial complexity, Planar graphs, Linear algebra in geometry, Another Euler's theorem, FFT, Bentley Ottmann algorithm, Linear time planarity check, Check if set has 3 collinear points in O(N log^3 N), Linear programming in 3/4 dimensions, a few more Euler's theorems and many more geometry algorithms.
As we all know, geometry is super common at IOI so it's important to know it really well. If you think you are good with basic geometry, you're very wrong.
This comment is a joke of course, as I assume the blog itself is one. For some stuff above we don't even know if it's possible to do it.
Bro specialists in China know this.
If you learn everything from this list you will be fine:(https://codeforces.me/blog/entry/92248)
SIO D1P2 is another proof that everything stated is true (except the note).
Yes
If you haven't heard of the Humpty, Dumpty, Queue and Sharky-devil points by age 13 you have no chance at solving an IOI Geometry problem.
Don’t forget the isoptic cubic
Of course, you also need everything NemanjaSo2005 said and the optimizations from this goated blog
You also need to know Miloš tree for processing 2d/3d points online in O(sqrt(n/log)*poly)/O(sqrt(n^(3/2)/log)*poly)
