Question

At the perpendicular at the point of contct to the circle passes thriugh centre

Answer 1

give- a circle of center o is drawn and AB is the tangent touching the circle at P.

construction- join OP

Take another point Q which is not passing through centre.

Now,angle OPB=90°

also angle QPB = OPB(each 90°)

angle QPB=90°(assume above)

it is only possible when Q and O are coincide
