DIRECTION : In the following questions, a statement of assertion (A) is followed by a
statement of reason (R). Mark the correct choice as:
Assertion : Sum of the pair of angles 1200 and 600 is supplementary.
Reason : Two angles, the sum of whose measures is 1800, are called supplementary angles.
  • a)
    Both assertion (A) and reason (R) are true and reason (R) is the correct explanation of assertion (A).
  • b)
    Both assertion (A) and reason (R) are true but reason (R) is not the correct explanation of assertion (A).
  • c)
    Assertion (A) is true but reason (R) is false.
  • d)
    Assertion (A) is false but reason (R) is true.
Correct answer is option 'A'. Can you explain this answer?
Verified Answer
DIRECTION : In the following questions, a statement of assertion (A) ...
We know that two angles are said to be supplementary if their sum of measure of angles is 1800.
So, Reason is correct.
Now, 1200 + 600 = 1800 ⇒ Sum of the pair of angles 1200 and 600 is supplementary.
So, Assertion is also correct.
Also, reason (R) is the correct explanation of assertion (A).
Correct option is (a) Both assertion (A) and reason (R) are true and reason (R) is the correct explanation of assertion (A).

DIRECTION : In the following questions, a statement of assertion (A) ...
Assertion: The sum of the pair of angles 120° and 60° is supplementary.
Reason: Two angles, the sum of whose measures is 180°, are called supplementary angles.

Explanation:
Supplementary angles are a pair of angles that add up to 180°. In this case, the angles mentioned in the assertion are 120° and 60°.

To verify if the assertion is true, we need to calculate the sum of these angles:
120° + 60° = 180°

As the sum of the angles is equal to 180°, the assertion is true.

The reason provided states that two angles, the sum of whose measures is 180°, are called supplementary angles. This is a true statement.

The angles 120° and 60° satisfy this condition as their sum is 180°. Therefore, the reason is also true.

Conclusion:
Both the assertion and the reason are true, and the reason correctly explains the assertion. Hence, the correct answer is option 'A'.
