投影點(正射影)與對稱點

C = (-1.3, -0.28)
B = (6.8, 3.46)
a = Line(C, B)
M: 0.5 * C + 0.5 * B
O: 0.5 * (Corner[1] + Corner[3])
P_1: (x(Corner[1]), y(O))
P_2: (x(Corner[2]), y(O))
P_3: (x(O), y(Corner[2]))
P_4: (x(O), y(Corner[3]))
u = Vector(P_1, P_2)
v = Vector(P_3, P_4)
A = (4.34, 4.22)
b = OrthogonalLine(A, a)
H = Intersect(b, a)
R = Mirror(A, a)
c = Segment(A, R)
α = Angle(B, H, A)

文字4: "H" + (LaTeX[H]) + ",R" + (LaTeX[R]) + ""
文字3: "A" + (LaTeX[A]) + ""
