90670 DIRECTION: In the following questions, a statement of assertion (A) is followed by a statement of reason (R). Mark the correct choice as:
Assertion: ABCis an isosceles triangle right angled at Cthen AB? = 2AC\(^{2}\)
Reason: If in atriangle, square of one side is equal to the sum of the squares of the other two sides, then the angle opposite the first side is a right angle. Ans. We know that If in a triangle, square of one side is equal to the sum of the.

1 Both assertion (A) and reason (R) are true and reason (R) isthe correct explanation of assertion (A).
2 Both assertion (A) and reason (R) are true but reason (R) is not the correct explanation of assertion (A).
3 Assertion (A) is true but reason (R) is false.
4 Assertion (A) is false but reason (R) is true.
