A carpenter is framing an opening in a wall to hang a rectangular door. Which properties must the door frame have to ensure that the door hangs properly? Check all that apply.The top and bottom are parallel.The top and right side form a right angle.The bottom and right side are congruent.The left side and right side are parallel.The left side and bottom form a right angle.

A rectangular door has opposite sides parallel and adjacent sides perpendicular. So the top and bottom are parallel, and the left and right sides are parallel. The top and right side, and the left side and bottom, meet at right angles. The bottom and right side do not have to be congruent; adjacent sides of a rectangle can have different lengths.
