What is EGMO 2018 Problem 5 Solution Analysis about?
The document presents the solution to a geometry problem. It proves that angle ABP equals angle QBC. It does this through three lemmas: 1) DE·DF equals DB^2, 2) DP·DQ equals DB^2, and 3) BI is the angle bisector of angle PBQ, where I is the incentre of triangle ABC. Using these lemmas and properties of angle bisectors and the incentre, it concludes that angle ABP equals angle QBC.
