In plane geometry, two rays that share a common endpoint and formed a figure is called angle and the two rays are called the sides of the angles. The endpoint of the rays called the vertex of the angle. The symbol angle is ∠. In general, angles are measured in degrees or in radians. A right angle is divided into 90 equal parts and each part is called a degree. A radian is an angle subtended at the centre of a circle by an arc equal in length to the radius of the circle. So take this quiz and know more about Angle.
