The angle subtended at the centre of a circle , by a chord whose length is equal to the radius of the circle will be

The angular subtended at the centre of the circle by an arc of length equal to the radius of circle is

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.

Find the angle subtended at the centre of a circle of radius 'a' by an arc of length (a pi/4)

Find the angle subtended at the centre of a circle of radius ' a ' by an arc of length (api//4) .

If the angles subtended by the chords of a circle at the centre of the circle are equal, then the chords are equal.

If the angle subtended by two chords of a circle at the centre are equal; the chords are equal.

If a chord of a circle subtends an angle of 30^(@) at the circumference of the circle, then what is the ratio of the radius of the circle and the length of the chord respectively?

If the angles subtended by two chords of a circle at the centre are equal,the chords are equal.

If the angles subtended by two chords of a circle at the centre are equal, then Prove chords are equal.
