Non-coplanar lines. They could be parallel or skew.For example, consider yourself facing a wall in a cuboid room. Line 1 = where the floor meets the wall in front of you, Line 2 = where the ceiling meets the wall in front of you, Line 3 = where the floor meets the wall behind you. Then Lines 1, 2 and 3 are parallel but not in the same plane.OrLine 4 = where the walls to the left and behind you meet. Lines 1 and 4 are not parallel nor in the same plane: they are skew.
The corner. Where the floor meets a wall. Or the ceiling meets the wall. In the window sill. In a door way.
The most common places to find cracks where the wall meets the ceiling are usually in the corners of rooms and along seams where different sections of drywall meet.
To repair a crack where the wall meets the ceiling, you can start by cleaning out the crack and removing any loose debris. Then, apply a flexible caulk or joint compound to fill in the crack. Smooth it out with a putty knife and let it dry completely. Sand the area lightly and repaint to blend it in with the rest of the wall and ceiling.
