how do I use ui.transform.rotation and anchor point on my vector shape

[resserone13v2.0]

want to rotate the shape and change the anchor point.

anchor point gives me error.

transform doesn't rotate the shape.

parallelogram.anchor_point(0,0)

# Rotate the parallelogram 180 degrees
		transform = ui.Transform.rotation(180)
		self.left_wall.transform = transform	

I want to rotate the parallelogram 180 degrees. here's the complete code

import ui
from scene import *


def parallelogram(a, angle_of_a, color,  x_pos, y_pos):
    
    b = a
    
    # Calculate the coordinates of points B and C
    angle_A_rad = math.radians(angle_of_a)
    bx = a
    by = 0
    cx = bx + b * math.cos(angle_A_rad)
    cy = b * math.sin(angle_A_rad)

    # Create a path to draw the parallelogram
    path = ui.Path()
    path.move_to(bx, by)  # Point B
    path.line_to(cx, cy)  # Point C
    path.line_to(cx - a,cy + a)  # Point D
    path.line_to(bx - a, by + a)  # Point A
    path.close()
    # Create a shape node with the path
    parallelogram = ShapeNode(path=path)
    parallelogram.fill_color = color
    parallelogram.stroke_color = 'black'
    parallelogram.position = (x_pos, y_pos)
    
    parallelogram.anchor_point(0,0)
    
    return parallelogram


class MyScene(Scene):
	def setup(self):
		self.background_color = 'white'
		self.left_wall = parallelogram(400, 100, 'orange', self.size.w / 2, self.size.h / 2)
		
                # Rotate the parallelogram 180 degrees
		transform = ui.Transform.rotation(180)
		self.left_wall.transform = transform		
		
		self.add_child(self.left_wall)

if __name__ == '__main__':
	run(MyScene(), show_fps=False)

@resserone13v2-0 error is "anchor_point is not callable..."

    parallelogram.anchor_point = (0,0)

Rotation angle is in radians

		transform = ui.Transform.rotation(math.pi)

ui.Transform is used with an ui.View, not a Node, use Action

		#transform = ui.Transform.rotation(math.pi)
		#self.left_wall.transform = transform		
		self.left_wall.run_action(Action.rotate_by(math.pi, 1, TIMING_EASE_IN_OUT))
