circlestangentdiameterassertion-reason
Question
**Assertion (A):** The tangents drawn at the end points of a diameter of a circle, are parallel.
**Reason (R):** Diameter of a circle is the longest chord.
Solution
1
Assertion is true (tangents at ends of diameter are perpendicular to the diameter, hence parallel to each other). Reason is true (diameter is the longest chord). But the reason does not explain why tangents are parallel.
