Perímetre del triangle equilàter és 6*raiz(3)*OE

On el segment OE és el radi del cercle inscrit !!

A = (0, -2)
B = (8, -2)
a = Segment(A, B)
b = LineBisector(A, B)
C = Point(b)
c = Segment(C, A)
d = Segment(C, B)
e = Segment(B, A)
f = LineBisector(C, B)
O = Intersect(f, b)
D = Point(c)
g = Circle(O, D)
Intersect(a, e)
Intersect(a, e)
Intersect(a, e)
E = Point(g)
h = Distance(O, E)
h 6 Root[3]
h 6 Root[3]
i = Distance(A, B)
