Carpenter Building with Parallel Lines

A carpenter sent his assistant to line up the wall studs (vertical boards) in my house. In doing so, all three studs were supposed to be parallel to each other and the walls. However, the assistant did not properly nail in the studs at the ceiling, and they shifted overnight. Using only the angle tool, help my carpenter re-align the studs. You can only use the angle tool where it fits between the walls/studs and the diagonal support. NOTE: To move a stud, click and drag points, E, G, or I. All other points are fixed. 1) Explain how you can use the left wall, right wall, and/or support beam with the angle tool to help you aligned each stud with the left and right wall, as well as the properties and angles you used. 2) Explain how you can use the floor and/or ceiling with the angle tool to help you align the studs so that they are parallel to the left and right wall.
