Question

Assertion (A): Tangents drawn at the end points of a diameter of a circle are always parallel to each other.
Reason (R): The lengths of tangents drawn to a circle from a point outside the circle are always equal.

Accepted Answer

Step 1: Both A and R are independently true. The reason tangents at endpoints of a diameter are parallel is that radius $\perp$ tangent, not equal tangent lengths. So R is not the correct explanation of A.
