Theorem 1: Radian is a constant angle

Theorem 2: The no.of Radians in an angle subtended by an arc of a circle at the centre = arc/radius

The number of radians in a 720-degree angle can be written as a pi , where a is a constant. What is the value of a ?

The angles of a quadrilateral are in A.P . If the ratio of the number of radians in the least angle to the number of degrees in the greatest angle be as pi : 1260 , find the angles in radians.

The angles in a triangle are in A.P. and the ratio of the smallest angle in degrees to the greatest angle in radians is 60:pi Find the angle of the triangle in degrees and radians.
