narysujte lubovolný uhol BAC

narysujte uhly veľkosti 45°, 180°, 90°

A = (-2.08, 2.18)
B = (2.88, 2.16)
a = Ray(A, B)
C = (0.8, 4.1)
b = Ray(A, C)
α = Angle(a, b)
D = (-2.24, -0.98)
E = (2.56, -0.98)
c = Ray(D, E)
E' = Rotate(E, 45.0°, D)
β = Angle(E, D, E')
F = (-1.94, -3.46)
G = (3.52, -3.42)
d = Ray(F, G)
G' = Rotate(G, 90.0°, F)
γ = Angle(G, F, G')
H = (-2.18, -5.22)
I = (3.16, -5.18)
e = Ray(H, I)
I' = Rotate(I, 180.0°, H)
δ = Angle(I, H, I')
