Symétrique d'une figure
Utilisation du quadrillage

Solution

En t'aidant du quadrillage trace la figure symétrique.

A = (-1, 6)
B = (-3, 6)
C = (-2, 5)
D = (-3, 4)
E = (-2, 1)
a = Segment(A, B)
b = Segment(B, C)
c = Segment(C, D)
d_1 = Segment(D, E)
e = Segment(E, A)
F = (1, 5)
G = (-3, 1)
d = Line(F, G)
A' = Mirror(A, d)
g = Segment(A, A')
B' = Mirror(B, d)
h = Segment(B, B')
C' = Mirror(C, d)
D' = Mirror(D, d)
k = Segment(D, D')
E' = Mirror(E, d)
j = Segment(E, E')
f = Segment(A', B')
l = Segment(B', C')
m = Segment(D', C')
n = Segment(E', D')
p = Segment(A', E')
i = Segment(C, B')
o = false
