Question 141 Mark
Assertion and Reason Type MCQ
Assertion: If three angles of a quadrilateral are 130°, 70° and 60°, then the fourth angles is 100°.
Reason: The sum of all the angle of a quadrilateral is 360°.
  1. Both Assertion (A) and Reason (R) are true and Reason is a correct explanation of Assertion (A).
  2. Both Assertion (A) and Reason (R) are true but Reason is not a correct explanation of Assertio (A).
  3. Assertion (A) is true and Reason (R) is false.
  4. Assertion (A) is false and Reason (R) is true.
Answer
  1. Both Assertion (A) and Reason (R) are true and Reason is a correct explanation of Assertion (A).
    Solution:
    Let the fourth angle be x.
    We know that the sum of all the angles of a quadrilateral is 360°.
    ⇒ 130° + 70° + 60° + x = 360°
    ⇒ x = 100°
    So, the fourth angles is 100°.
    Thus, the Assertion (A) is true.
    The reason (R) is alos true and is the correct explanation for the Assertion (A).

Question 451 Mark
Assertion and Reason Type MCQ
Assertion: Every parallelogram is a rectangle.
Reason: The angle bisectors of a parallelogram form a rectangle.
  1. Both Assertion (A) and Reason (R) are true and Reason is a correct explanation of Assertion (A).
  2. Both Assertion (A) and Reason (R) are true but Reason is not a correct explanation of Assertio (A).
  3. Assertion (A) is true and Reason (R) is false.
  4. Assertion (A) is false and Reason (R) is true.
Answer
  1. Assertion (A) is false and Reason (R) is true.
    Solution:
    Every parallelogram need not be rectangle, since a parallelogram could be a square, or a rhombus too.
    So, the Assertion (A) is false.
    The angle bi sectors of a parallelogram form a rectangle.
    So, the Reason (R) is true.
