How can one safely rappel using only a rope?

To safely rappel using only a rope, you should first ensure the rope is securely anchored to a strong and stable point. Next, wear a harness and helmet, and use a belay device to control your descent. Maintain three points of contact with the rope at all times and descend slowly and steadily, keeping your body perpendicular to the ground. Practice proper rappelling techniques and always have a backup plan in case of emergencies.
