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 shaft of a motor car rotates at constant angular frequancy of 3000 revolutions //min .The angle through which it has turned in one second in radians is

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.

Assertion : Radian is the unit of distance. Reason : One radian is the angle subtended at the centre of a circle by an arc equal in length to the radius of the circle.

Theorem 1the sum of the angles of a quadrilateral is 360^(@) or 4 right angles.

By decreasing 15^(@) of eqch angle of a triangle the ratios of their angles are 2:3:5 the radian meausre of greatest angle is

If the perimeter of a sector of a circle is twice the diameter of the circle, then the radian measure of the angle of the sector is

A circular are of radius 1 subtends an angle of x radians 0 0)(T(x))/(S(x))
