These varieties include ANGULAR separation of bounding planes, ANGULAR spacing conditions related to circle, digression from a basic direction etc. Because of these diverse geometrical forms, different types of methods and equipment are available to measure angles in common ANGULAR units of degree, minute and second.
measuring devices and the techniques used in determining the angle. In addition to that, we will have an overview of angle comparators (autocollimators). Objectives After studying this unit, you should be able to familiarise yourself with various types of angular measuring devices, and
