    How to name an angle?

    There are three ways in which an angle can be named. They are as follows:

    (i) Name of the vertex

    Acute angle of 60o

    Here, the rays BA and BC form a 60angle at the vertex ‘B’. Hence, we name this angle

    as ∠B.

    Angle B

    But when more than 2 rays converge at the same point, they form more than 1 angle. Hence, naming each angle using the vertex may lead to confusion.
