Drawing a Sierpinski triangle using GUI\/Turtle.<\/p>\n\n\n\n

Write a program that draws Sierpinski triangle using recursive methods as shown below:<\/p>\n\n\n\n

The three points of the triangle are passed to invoke displayTriangles. If order == 0, the displayTriangles (order, p1, p2, p3) function displays a triangle that connects three points p1, p2, and p3, as shown in Figure a. Otherwise, it performs the following tasks:<\/p>\n\n\n\n

  1. Obtains a midpoint between p1 and p2), a midpoint between p2 and p3, and a midpoint between p3 and p1, as shown in Figure b.<\/li>\n\n\n\n
  2. Recursively invokes displayTriangles with a reduced order to display three smaller Sierpinski triangles. Note that each small Sierpinski triangle is structurally identical to the original big Sierpinski triangle except that the order of a small<\/li>\n<\/ol>\n\n\n\n

    triangle is one less, as shown in Figure b.<\/p>\n\n\n\n

    Drawing a Sierpinski triangle spawns calls to draw three small Sierpinski triangles recursively.<\/p>\n\n\n\n

    Once done, rewrite the programs for filled Sierpinski triangles.<\/p>\n\n\n\n

    The Correct Answer and Explanation is :<\/strong><\/mark><\/p>\n\n\n\n

    he Sierpinski Triangle is a fractal pattern formed by recursively subdividing an equilateral triangle into smaller equilateral triangles.his process results in a self-similar structure, where each smaller triangle mirrors the overall shape.mplementing this pattern in Python using the Turtle graphics library allows for a visual demonstration of recursion and fractal geometry.
    Understanding the Recursive Process:<\/strong><\/p>\n\n\n\n

    . Base Case (Order 0):<\/strong> Draw a single equilateral triangle.. Recursive Case (Order > 0):<\/strong> Divide the current triangle into three smaller triangles by connecting the midpoints of its sides. Recursively apply the same process to each of the three smaller triangles.
    Python Turtle Implementation:<\/strong><\/p>\n\n\n\n

    “python
    import turtle<\/p>\n\n\n\n

    def draw_triangle(points, color, my_turtle):
    “””Draws a filled triangle with the given points and color.”””
    my_turtle.fillcolor(color)
    my_turtle.up()
    my_turtle.goto(points[0][0], points[0][1])
    my_turtle.down()
    my_turtle.begin_fill()
    my_turtle.goto(points[1][0], points[1][1])
    my_turtle.goto(points[2][0], points[2][1])
    my_turtle.goto(points[0][0], points[0][1])
    my_turtle.end_fill()<\/p>\n\n\n\n

    def get_mid(p1, p2):
    “””Calculates the midpoint between two points.”””
    return ((p1[0] + p2[0]) \/ 2, (p1[1] + p2[1]) \/ 2)<\/p>\n\n\n\n

    def sierpinski(points, degree, my_turtle):
    “””Recursively draws the Sierpinski triangle.”””
    colormap = [‘blue’, ‘red’, ‘green’, ‘white’, ‘yellow’, ‘violet’, ‘orange’]
    draw_triangle(points, colormap[degree], my_turtle)
    if degree > 0:
    sierpinski([points[0],
    get_mid(points[0], points[1]),
    get_mid(points[0], points[2])],
    degree-1, my_turtle)
    sierpinski([points[1],
    get_mid(points[0], points[1]),
    get_mid(points[1], points[2])],
    degree-1, my_turtle)
    sierpinski([points[2],
    get_mid(points[2], points[1]),
    get_mid(points[0], points[2])],
    degree-1, my_turtle)<\/p>\n\n\n\n

    def main():
    “””Sets up the Turtle environment and starts the drawing.”””
    my_turtle = turtle.Turtle()
    my_win = turtle.Screen()
    my_points = [[-100, -50], [0, 100], [100, -50]]
    sierpinski(my_points, 3, my_turtle)
    my_win.exitonclick()<\/p>\n\n\n\n

    if name<\/strong> == ‘main<\/strong>‘:
    main()<\/p>\n\n\n\n

    **Explanation of the Code:**\n\n. **`draw_triangle` Function:** This function takes three points and a color as input, moves the turtle to the first point, and draws a filled triangle connecting all three points.. **`get_mid` Function:** Given two points, this function calculates and returns their midpoint, which is essential for subdividing the triangle.. **`sierpinski` Function:** This is the core recursive function. It draws a triangle and, if the recursion depth (`degree`) is greater than zero, it calculates the midpoints of the triangle's sides and recursively draws three smaller triangles at each corner. The `colormap` list assigns different colors to triangles at different recursion levels, enhancing the visual appeal.. **`main` Function:** Sets up the Turtle graphics environment, defines the initial points of the large equilateral triangle, and starts the recursive drawing process.\n**Running the Program:**\n\no execute this program, ensure you have Python installed on your system. Save the code in a file named `sierpinski.py` and run it using the command:\n``bash\npython sierpinski.py<\/code><\/pre>\n\n\n\n
    his will open a window displaying the Sierpinski Triangle with a depth of 3. You can adjust the depth by changing the second argument in the sierpinski<\/code> function call within the main<\/code> function.
