'Return the current tilt-angle.
No argument.
Return the current tilt-angle, i. e. the angle between the
orientation of the turtleshape and the heading of the turtle
(its direction of movement).
Examples (for a Turtle instance named turtle):
>>> turtle.shape("circle")
>>> turtle.shapesize(5,2)
>>> turtle.tilt(45)
>>> turtle.tiltangle()'

def tiltangle(self):

    tilt = (((- self._tilt) * (180.0 / math.pi)) * self._angleOrient)
    return ((tilt / self._degreesPerAU) % self._fullcircle)
