If the angle between two tangents drawn from an external point P to a circle of radius 'a' and center O , is `60^(@),` then find the length of OP.

If angle between two tangents drawn from a point P to a circle of radius a and centre 0 is 60^(@) then OP=asqrt3 .

If angle between two tangents drawn from a point P to a circle of radius 'a' and the centre O is 90^(@) then prove that OP=sqrt(a)

Write true or false and state reason If angle between two tangents drawn from a point P to a circle of radius a and centre 0 is 90^(@) then OP=asqrt2 .
