Question

Write 'True' or 'False' and justify your answer in each of the following:


If a chord AB subtends an angle of 60° at the centre of a circle. then angle
between the tangents at A and B is also 60°.


The length of tangent from an external point on a circle is always greater than
the radius of the circle.


3. The length of tangent from an external point P on a circle with centre o is
always less than OP.


4. Can The angle between two tangents to a circle can be zero.


5. If angle between two tangents drawn from a point P to a circle of radius a
and centre O is 90°, then OP ?


6. If angle between two tangents drawn from a point P to a circle of radius a
and centre 0 is 60°, then OP = ?
​

Answer 1

Answer:

1. False, the angle between the tangents will be half
