Write a function that returns True if the rotation from AB onto AC is counter-clockwise (ccw).
A, B, C are points in the xy-plane...
def is_ccw(A, B, C):
# .....Read points from the points.txt text file in this folder. Each line contains a tuple with three 2D points. Each point is a tuple of 2 floats (x,y), e.g. ((1895.0943, 2291.517), (589.296, 207.324), (1360.998, 1611.965)).
Calculate and print out is_ccw for each tuple of points.
Given a point P and a normal that span a plane in 3D space, return an arbitrary vector that rests within that plane.
