首先，我們需要確定五個角的座標，

#繪製多邊形
from tkinter import *
import math as m

root = Tk()
w = Canvas(root,width=200,height=150,background="red")
w.pack()
center_x = 100
center_y = 70
r=50
points =[
    #左上點
    center_x - int(r * m.sin(2 * m.pi / 5)),
    center_y - int(r * m.cos(2 * m.pi / 5)),
    # 右上點
    center_x + int(r * m.sin(2 * m.pi / 5)),
    center_y - int(r * m.cos(2 * m.pi / 5)),
    # 左下點
    # center_x - int(r * m.sin(m.pi / 5)),
    # center_y + int(r * m.cos(m.pi / 5)),
    center_x - int(r * m.sin(m.pi / 5)),
    center_y + int(r * m.cos(m.pi / 5)),
    # 頂點
    center_x,
    center_y - r,
    #右下點
    center_x + int(r * m.sin(m.pi / 5)),
    center_y + int(r * m.cos(m.pi / 5)),
]
w.create_polygon(points,outline="green",fill="yellow")
mainloop()
