What units protractor?
A protractor is typically used to measure angles in degrees. It consists of a semicircular or circular scale marked from 0 to 180 degrees (or 0 to 360 degrees in a full protractor). Some protractors also include measurements in radians, but the degree is the most common unit. The accuracy of angle measurement can vary based on the protractor's design and quality.

What is the semi circle ruler called?
The semi-circle ruler is commonly known as a protractor. A protractor is a geometric tool used to measure and draw angles. It typically has a half-circle shape with degree markings along the curved edge.
How do you measure angles with a protractor?
A protractor is a shape: semi-circle or full circle, that has degrees marked around the edge. Place the marked centre of the protractor on (for example) the corner of two lines forming a right-angle. The bottom line will be zero, while the vertical line will cross the 90 degrees mark of the protractor, so proving that a right-angle is 90 degrees.
