三角測量(12)隔著湖測建築物寬度
Author: 藍邦偉  老師

由湖邊A,B兩點，測對岸C,D兩點的距離。

三角測量(12)

A = (-2.66, -0.92)
C = (1.46, 3.08)
D = (9.76, 3.04)
a = Segment(C, D)
b = Segment(C, A)
c = Segment(A, D)
α = Angle(A, C, D)
β = Angle(C, D, A)
B = (1.7, -2.4)
g = Segment(C, B)
h = Segment(B, D)
γ = Angle(D, C, B)
δ = Angle(C, D, B)
