turtle.forward(g*2)
turtle.right(120)
turtle.backward(g)
turtle.right(60)
turtle.end_fill()

turtle.penup()
turtle.forward(g*3)
turtle.left(120)
turtle.forward(g)
turtle.pendown()

turtle.begin_fill()
turtle.fillcolor("red")
turtle.forward(g)
turtle.left(60)
turtle.forward(g)
turtle.right(120)
turtle.backward(g)
