python rotating object disfunction

Question

I have been working on my final project, where we are supposed to create a tank game in tkinter. I have done the movement, however i´ve been struggling with the rotation of my tank. Yesterday, I manually calculated all the x and y coordinates for rotation and it works, but for some reason, when i rotate the tank for example to left, back to normal(till here it works) and then to left again the tank just completely messes up. Can´t think of reason why this is happening. Would appreciate some help. Here is my code :

from tkinter import *
x=0
y=0
poloha="hore"
class Tank:

    def __init__(self, delta) -> None:
        """""
        x=input("Enter position of tank(x):")
        y=input("Enter position of tank(y):")
        """""
        self.t1 = plocha.create_rectangle(int(x)+50,int(y)+375,int(x)+100,int(y)+425)
        self.t2 = plocha.create_rectangle(int(x)+45,int(y)+370,int(x)+50,int(y)+430)
        self.t3 = plocha.create_rectangle(int(x)+100,int(y)+370,int(x)+105,int(y)+430)
        self.t4 = plocha.create_rectangle(int(x)+72.5,int(y)+350,int(x)+77.5,int(y)+400)
        self.delta = delta
