1.  Play with points A and B making the angle and circle bigger and smaller.
2.  Record 3 sets of measurements for the central angle and it's inscribed arc.
3.  What do you notice about the relationship?

A = (1.58, 0.78)
B = (3.5, 3.64)
c = Circle(A, B)
C = Point(c)
a = Segment(B, A)
b = Segment(A, C)
α = Angle(C, A, B)

text2: "Arc BC: " + α + ""
