Which of the following is used in checking the instruments to measure angles with great accuracy? Correct Answer Circular Vernier scale

The circular Vernier scale is used to check the instruments to measure angles with high accuracy. They are used in measuring instruments like micrometer in mechanical engineering. They work on the same principle as the linear Vernier scale.
