Question

The tangent at any point to a circle is to the radius through the point of contact​

Answer 1

Step-by-step explanation:

• So OA is shorter than any other line segment joining O to any point on l. Hence, the tangent at any point of a circle is perpendicular to the radius through the point of contact.

Answer 2

● The tangent at any point of a circle is perpendicular to the radius through the point of contact.
