Answer 1

Answer:

Both Assertion and Reason are correct statements and Reason is the correct explanation of Assertion.

Answer 2

SOLUTION

TO CHOOSE THE CORRECT OPTION

Assertion : Sum of the pair of angles like (120,° 60° )is supplementary.

Reason : Two angles, the sum of whose measures is 180° are called supplementary angles.

(a) Both assertion and reason are true and reason is the correct explanation of assertion.

(b) Both assertion and reason are true but reason is not the correct explanation of assertion.

(c) Assertion is true but reason is false.

(d) Both assertion and reason are false

EVALUATION

Assertion :

Sum of the pair of angles like (120,° 60° )is supplementary.

The assertion is true as we know that two angles are said to be supplementary if sum of the angles = 180°

Reason :

Two angles, the sum of whose measures is 180° are called supplementary angles.

The reason is true

As 120° + 60° = 180°

And we know that two angles are said to be supplementary if sum of the angles = 180°

So the two angles are supplementary

Also reason is the correct explanation of assertion.

FINAL ANSWER

Hence the correct option is

(a) Both assertion and reason are true and reason is the correct explanation of assertion
