a BENTECH presentation.......
Equal chords are equidistant from the 
centre of the circle

drag A or B to change the chord
 to get various cases....

Drag_me = 3.5 (slider from 0.5 to 5, step 0.1)
A_1 = (8.976, 0.707999999999999)
c = Circle(A_1, Drag_me)
B_1 = Point(c)
B = Point(c)
A = Point(c)
t = Segment(B, A)
f = OrthogonalLine(A_1, t)
G = Intersect(f, t)
η = Segment(A_1, G)
H = Point(c)
a = Line(H, A_1)
Q = Mirror(B, a)
P = Mirror(A, a)
β = Segment(Q, P)
b = OrthogonalLine(A_1, β)
C = Intersect(b, β)
δ = Segment(A_1, C)
F = Midpoint(G, A_1)

I = Midpoint(C, A_1)
J = Midpoint(A_1, G)
