Question

Assertion (A): The tangents drawn at the end points of a diameter of a circle are parallel to each other.

Reason (R): A tangent to a circle is perpendicular to the radius through the point of contact.

Options

• Both Assertion (A) and Reason (R) are true and Reason (R) is a correct explanation of Assertion (A).

• Both Assertion (A) and Reason (R) are true but Reason (R) is not a correct explanation of Assertion (A).

• Assertion (A) is true and Reason (R) is false.

• Assertion (A) is false and Reason (R) is true.

Answer 1

Both Assertion (A) and Reason (R) are true and Reason (R) is a correct explanation of Assertion (A).

Explanation:

Both A and R are true. At each endpoint of a diameter, the tangent is perpendicular to the radius and each radius lies on the diameter. Thus, both tangents are perpendicular to the same line and are therefore parallel. R correctly explains A.
