In the "Tell Turtle's state" section
(https://docs.python.org/3/library/turtle.html#tell-turtle-s-state) I
would think that you could roll your own function by using your
knowledge of the coordinates of where the turtle is at and the
turtle.towards(0, 0).  By computing your own angle (knowing what units
you are using) and comparing with what is returned you should be able
to determine what angular units are currently set.

HTH!
