What is a "ruler"?
A ruler is a straight, flat tool used to measure length or draw straight lines. It is typically made of wood, plastic, or metal and is marked with units of measurement, such as inches or centimeters. Rulers are commonly used in schools, offices, and workshops for tasks that require accurate measurements, like drawing, crafting, or construction. They come in different sizes and styles, including flexible or rigid versions, and some may have additional features like marked angles for geometric work. Rulers are simple but essential tools for a wide range of activities.
