Assertion: The sum of either pair of opposite angles of a cyclic quadrilateral is 180º.
Reason: Two or more circles are called concentric circles if and only if they have different centre and radii.
Explanation:
A cyclic quadrilateral is a quadrilateral whose vertices all lie on a single circle. In other words, the circumcircle of a cyclic quadrilateral passes through all four vertices of the quadrilateral. Let's analyze the given assertion and reason in detail:
Assertion: The sum of either pair of opposite angles of a cyclic quadrilateral is 180º.
In a cyclic quadrilateral, opposite angles are supplementary, which means they add up to 180º. This property can be proven using the fact that opposite angles in a cyclic quadrilateral are subtended by the same arc on the circumcircle.
Reason: Two or more circles are called concentric circles if and only if they have different centre and radii.
This reason is not directly related to the assertion and does not provide a correct explanation. The reason talks about concentric circles, which are circles that share the same center but have different radii. However, this concept is not relevant to the sum of opposite angles in a cyclic quadrilateral.
Conclusion:
The assertion is true because opposite angles in a cyclic quadrilateral are supplementary. However, the reason is false as it does not provide a correct explanation for the assertion. Hence, the correct answer is option 'C' - Assertion is true but reason is false.
Reason: Two or more circles are called concentric circles if and only if they have different centre and radii.
