Assertion and reasoning II — task. Maths CBSE Live product, Class 7.

Assertion(A): If \(\angle a = 63^{\circ}\) is the alternate exterior angle of \(\angle b\), then \(\angle a = b = 63^{\circ}\).

Reason(R): Alternate exterior angles are equal only when a transversal cuts two parallel lines.

Assertion(A) and Reason(R) are true and Reason(R) is the correct explanation of Assertion(A).
Assertion(A) and Reason(R) are true and Reason(R) is not the correct explanation of Assertion(A).
Assertion(A) is true but Reason(R) is false.
