About Protractor Tool
A protractor is a tool used to measure angles, typically in degrees. It is a semicircular or circular tool marked with degrees from 0° to 180° or 0° to 360°. Protractors are commonly used in geometry, trigonometry, engineering, and drafting for constructing and measuring angles. This online protractor tool helps you visualize and understand angles by inputting a degree value and seeing it represented graphically. It's a simple and effective way to learn about and work with angles.
- Degrees (°): The unit of measurement for angles. A full circle is 360°.
- Right Angle: An angle of exactly 90°.
- Straight Angle: An angle of exactly 180°.
- Acute Angle: An angle less than 90°.
- Obtuse Angle: An angle greater than 90° but less than 180°.
