Geometry Problem 1237: IMO 2016, Problem 1, Triangle, Congruence, Parallel Lines, Concurrency.

Triangle CBF has a right angle at B. A is a point on line CF extended such that FA = FB. Point D is chosen such DA = DC and AC is the bisector of angle DAB. Point E is chosen such that EA = ED and AD is the bisector of angle EAC. Let M be the midpoint of CF. Let X be a point on ED extended such that MX is parallel to AE. Prove that lines BD, FX, and ME are concurrent.
