Final answer:
Wooden folding rules are good for measuring vertical distances because they are rigid and can provide accurate measurements when measuring along a vertical plane.
Step-by-step explanation:
Wooden folding rules are good for measuring vertical distances because they are rigid and can provide accurate measurements when measuring along a vertical plane. Unlike tape measures, which are flexible and can sag or bend when measuring vertically, wooden folding rules maintain their shape and stay straight, allowing for more precise measurements.
For example, if you need to measure the height of a wall or the distance between two points along a vertical line, a wooden folding rule can be extended along the vertical plane without any sag or deviation, providing a reliable measurement. The folding mechanism also allows for easy storage and transport, making it convenient to carry around.
In conclusion, wooden folding rules are ideal for measuring vertical distances due to their rigidity, accuracy, and ease of use.
