The correct Answer is:
To solve the question regarding the instrument in a geometry box that has the shape of a semicircle, we can follow these steps: ### Step-by-Step Solution: 1. **Understand the Definition of a Semicircle**: A semicircle is half of a circle. It is formed by cutting a whole circle along its diameter. The shape resembles a half-moon or the letter "D". 2. **Identify Geometry Instruments**: In a geometry box, there are several instruments, such as a ruler, compass, protractor, and divider. We need to determine which of these instruments is shaped like a semicircle. 3. **Analyze the Instruments**: - **Ruler**: A straight edge used for measuring lengths; it is not semicircular. - **Compass**: Used for drawing arcs and circles; it has two arms but does not have a semicircular shape. - **Divider**: Similar to a compass but used for measuring distances; it is also not semicircular. - **Protractor**: This instrument is used for measuring angles and is typically shaped like a semicircle, with markings from 0° to 180°. 4. **Conclusion**: The instrument in a geometry box that has the shape of a semicircle is the **protractor**. ### Final Answer: The instrument in a geometry box having the shape of a semicircle is the **protractor**. ---
