Open in App
Solution
We know the property of radius being perpendicular to tangent, but where is it perpendicular? At their point of intersection of course. The point of intersection of radius and tangent is at the point of contact of the tangent. Hence radius of a circle and tangent are perpendicular at the point of contact.
