Now, let's rotate our triangle about the origin. The origin is the point (0, 0).

We must rotate the triangle until it covers the target triangle.

• Go to and drag Rotate about Origin into your program, then click Run.
• Change the number in sprite.rotate_origin(45) until the triangle overlaps with the target triangle.

• Click Submit and Next once the triangle overlaps the target.
