Sur une idée de Vincent Pantaloni

But : Trouver des valeurs approchées de √2 sous forme de fractions.

Vous devriez trouver successivement 4 / 3, 7 / 5, 10 / 7, 17 / 12…

√2 étant irrationnel, aucun des coins des carreaux supérieurs ne tombera exactement sur un des coins des carreaux inférieurs.


import turtle

t = turtle
data = (45, (90, -90)), (0,(-90,-90,90,90))

for d in data:
 t.penup()
 t.goto(-160,0)
 t.pendown()
 t.setheading(0)
 i = 0
 while t.position()[0] < 160:
  t.left(d[0] if i == 0 else d[1][i % len(d[1])])
  t.fd(8)
  i += 1
