4. (10 points) Use the GCP approach to design a four-bar linkage to guide a door through the three positions shown. Position 1 is horizontal, and position 3 is vertical.

As a tentative design, she selects point B* as a center point and A as a circle point. For the three positions shown, determine the location of the circle point B corresponding to the center point B* and the center point A*corresponding to the circle point A. Animate the linkage to see if there is any branch defect in the solution. a) Submit a screenshot of the final drawing with dimensions of the unknown parameters illustrated clearly. b) Write your final answer in the table below.
