If a chord `AB` subtends and angle of `60^(@)` at the centre of a circle, then the angle between the tangents to the circle drawn from `A` and `B` is

If chord AB subtends an angle 50^(@) at the centre of a circle then the angle between the tangents at A and B is

If a chord PQ subtends an angle of 80^@ at the centre of a circle, then angle between the tangents at P and Q is also 80^@ State true or false

If a chord AB subtends an angle of 60^(@) at the centre of a circle, the angle between the tangents at A and B is also 60^(@) . Write ‘True’ or ‘False’ and justify.
