1. **Problem statement:** Follow the given commands to trace the robot's path for program (a)(ii). 2. **Commands given:** - Pencil down (start drawing) - Move 4 cm forward - Turn CCW (90° counterclockwise) - Move 2 cm forward - Turn CW (90° clockwise) - Move 2 cm forward - Turn CW (90° clockwise) - Move 6 cm forward - Turn CW (90° clockwise) - Move 6 cm forward - Turn CW (90° clockwise) - Move 4 cm forward 3. **Step-by-step path tracing:** - Start facing right (assumed initial direction). - Move 4 cm right. - Turn CCW: now facing up. - Move 2 cm up. - Turn CW: now facing right. - Move 2 cm right. - Turn CW: now facing down. - Move 6 cm down. - Turn CW: now facing left. - Move 6 cm left. - Turn CW: now facing up. - Move 4 cm up. 4. **Shape formed:** The robot draws a closed shape starting at the origin, moving right 4 cm, up 2 cm, right 2 cm, down 6 cm, left 6 cm, and up 4 cm, forming an irregular polygon resembling a step shape. 5. **Summary:** The robot's path is a polygon with vertices at (0,0), (4,0), (4,2), (6,2), (6,-4), (0,-4), and back up to (0,0) after the last move. Final answer: The robot draws a closed polygon with the described path following the commands exactly.
