MCQ

Assertion : If two lines intersect, then the vertically opposite angles are equal. Reason : If a transversal intersects, two other parallel lines, then the sum of two interior angles on the same side of the transversal is $180^\circ .$

A
Both Assertion and Reason are correct and Reason is the correct explanation for Assertion.
✓
Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion.
C
Assertion is correct but Reason is incorrect.
D
Both Assertion and Reason are incorrect.

✓

Answer

Correct option: B.

Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion.

When a transversal intersects two parallel lines, the angle made on the interior same side is $180$ degrees.
So, both are facts but reason does not explain assertion correctly.
