Draw the flag of the Bahamas in the center of the canvas. The flag is 600 units wide and 300 units high.

The flag has three horizontal stripes of equal height. Color the top and bottom stripes teal (#00778B). Color the middle stripe golden yellow (#FFC72C). Draw a black (#000000) border around the flag and middle stripe.

Add a black (#000000) equilateral triangle on the left. Its base follows the flag’s left edge. Join the points (-300, 150), (-300, -150), and about (-40, 0).

Use draw_centered_rectangle(x0, y0, width, height, color) to draw the flag and its middle stripe. The x0 and y0 values give each rectangle’s center.
