We'll take a look at geometry of angles in the tropical plane by means of the tropical wave front evolution. Resulting caustic produces a subdivision of the tropical angle to the elementary (right) angles. If both bounding rays of the angle are rational then the angle corresponds to a toric surface singularity, and the caustic subdivision corresponds to the minimal toric resolution. Otherwise, the subdivision is infinite. Joint work with Mikhail Shkolnikov.
