Think of a pizza slice or Pacman as the shape that can be returned. '''maxA and minA are defined in degrees'''. These values can be any number, however it is important to realize that they are used to generate a random point in a circle. maxA set to 540 for instance would simply result in a higher probability of the point returning in the right half of the circle compared to the left half.
