Every morning Ann walks her dog through the park, shown as a green square on the diagram below. They start at point 1, walk one block up the street, take a turn at the corner labeled 2, and walk diagonally through the park to point 3. To return home, they walk two blocks down the street and turn right at the corner labeled 4. Draw the path 1?2?3?4?1 taken by Ann as she walks her dog. Represent each segment of Anna's walk with a vector. The vectors should start and end at the centers of the red dots located on the image.
