    turtle.up()
    turtle.goto(x,y)
    turtle.down()
    
mygoto(-250,75)
turtle.begin_fill()
for i in range(5):
    turtle.forward(100)
    turtle.right(144)
turtle.end_fill()

mygoto(-100,150)
turtle.begin_fill()
for i in range(5):
    turtle.forward(50)
    turtle.right(144)
turtle.end_fill()

mygoto(-80,80)
turtle.begin_fill()
for i in range(5):
