Answer 1

Answer:

1.The common end point is called the Vertex and rays OA and OB are the arms of the angle.2.The names of basic angles are Acute angle, Obtuse angle, Right angle, Straight angle, reflex angle and full rotation. An angle is geometrical shape formed by joining two rays at their end-points.
