construir un triángulo con esas medidas

a = 3 (slider from 1 to 12, step 0.1)
b = 5 (slider from 1 to 12, step 0.1)
c = 6 (slider from 1 to 12, step 0.1)
A = (3, 5)
B = (3, 4)
C = (3, 3)
d = Circle(A, a)
e = Circle(B, b)
f = Circle(C, c)
D = Point(d)
aa = Segment(A, D)
E = Point(e)
bb = Segment(B, E)
F = Point(f)
cc = Segment(C, F)
G = (3, -3)
g = Circle(G, c)
H: G + (1, 0)
h = Ray(G, H)
k = Circle(G, b)
I = Intersect(g, h, 1)
p = Circle(I, a)
J = Intersect(k, p, 1)
polígono1, j, g_1, i = Polygon(G, I, J)
l = false
condi: Max[{a, b, c}] ≥ (a + b + c) / 2
