Question: Geometry tool used to measure the size of an angle in degrees?
The geometry tool used to measure the size of an angle in degrees is a protractor.
A protractor is a semi-circular tool with markings in degrees. To measure an angle with a protractor, place the center of the protractor at the vertex of the angle and align one of the sides of the angle with the baseline of the protractor. Then, read the measurement where the other side of the angle intersects the protractor. The measurement is usually given in degrees, ranging from 0° to 180° or 360°, depending on the type of angle.
Protractors are a common tool used in geometry classes and by professionals in fields such as engineering and architecture. They are also used by hobbyists, such as quilters and woodworkers, to make precise measurements.
Here are some tips for using a protractor:
- Make sure that the protractor is centered at the vertex of the angle.
- Align one of the sides of the angle with the baseline of the protractor.
- Read the measurement where the other side of the angle intersects the protractor.
- If the angle is more than 180°, use the other side of the protractor to measure the angle.
With a little practice, you can use a protractor to measure angles accurately and easily.
