Question

Prove that the perpendicular at the point of contact to the tangent to a circle passes through the centre....​

Answer 1

Step-by-step explanation:

pls mark it as a brainiliest

Answer 2

Step-by-step explanation:

given: letters assume a circle with centre at AB the tangent intersecting circle at point P .

to prove:OP_AB

proof: Vinod that tangent of a circle is perpendicular to radius at point of contact .

hence op-ab

now let's assume some point x ,such that XP- AB hence,xpb =90 degrees

opb=xpb=90 degree

which is possible only if line XP passes through o

hence, perpendicular to tangent passes through centre ..,.........
