geometrician
Studies angles professionally
A geometrician is a person who studies or specializes in geometry—the branch of mathematics dealing with points, lines, angles, surfaces, and solids.
The term is more formal than "geometer" and less common in modern usage: The geometrician demonstrated the proof on the blackboard.
