class 6 Mathematics Textbook Chapter 2 question answer
An angle is created when two rays originate from the same point. The rays are the arms of the angle, while the shared point is the vertex. For instance, in ∠ABC, BA and BC are the arms, and B is the vertex. Angles measure the rotation between the arms and are denoted using symbols like ∠ABC. Common examples include angles in scissors, a book’s opening, and turning door hinges.
