Receipt for the Angle Bisector Theorem
In geometry, the angle bisector theorem is concerned with the relative lengths of the two segments that a triangle's side is divided into by a line that bisects the opposite angle.
The kiosk interprets this as proof that every moon-pie can be divided by a very polite diagonal, provided nobody asks what the diagonal wants.
