What is the function of a Protractor?

• A. A tool to measure distances
• B. An instrument for measuring angles
• C. A device for determining weight
• D. A type of welding apparatus

Answer: (B)

The function of a protractor is specifically to measure angles, making the choice of an instrument for this purpose the correct one. Protractors are typically semicircular or circular devices marked with degree measurements from 0 to 180, or 0 to 360 degrees. Utilizing a protractor allows for precise angle measurements, which is essential in various fields such as drafting, geometry, engineering, and woodwork. This measurement capability makes it a crucial tool for anyone needing to assess or create angles accurately. In contrast, the other options refer to tools that serve entirely different purposes. For example, tools to measure distances would generally be rulers or tape measures, while a device for determining weight would reside in tools like scales. Lastly, a welding apparatus is a type of equipment used for joining materials together through high heat and is unrelated to measurement tasks. Each of these alternatives highlights distinct tools and their respective functionalities, emphasizing the unique role of a protractor in angle measurement.
