Describing an Object 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.

To ensure that a rectangular door hangs properly, the door frame must have the following properties:<br /><br />1. **The top and bottom are parallel.** <br /> - This ensures that the door can open and close smoothly without binding.<br /><br />2. **The left side and right side are parallel.** <br /> - This ensures that the door fits evenly within the frame and maintains its rectangular shape.<br /><br />3. **The top and right side form a right angle.** <br /> - This ensures that the corners of the frame are square, which is necessary for the door to fit properly.<br /><br />4. **The left side and bottom form a right angle.** <br /> - Similar to the previous point, this ensures that the corners are square.<br /><br />The property "The bottom and right side are congruent" is not necessary for ensuring the door hangs properly, as congruency refers to equal length, which is not required for a rectangular frame.
