I hope that is ok now...I created the algorithm below, but I need the loop...but I cannot understand how to do them ...

#   draw three triangle of triangles
from turtle import *
 
# draw a triangle
for sides in range(1, 4) :
    forward(10)
    left(120)
 
#  move to position for second triangle
penup()
forward(5)
right(120)
 
pendown()
#  draw a triangle
for sides in range(1, 4) :
    forward(20)
    left(120)
#  move to position for second triangle
penup()
forward(20)
left(120)
forward(10)
right(120)
pendown()
#  draw a triangle
for sides in range(1, 4) :
    forward(30)
    left(120)
