Question

6. Give the reason why :
(i) two obtuse angles cannot be supplementary?
(ii) two acute angles cannot be supplementary?
(iii) two right angles are supplementary?​

Answer 1

Answer:

Only 2 90 degree angles can be supplementary. Anything less or more will not work.

Step-by-step explanation:

180/2=90. So two obtuse angles could not be supplementary as obtuse angles are more than 90 degrees. Similarly, acute angles are less than 90 degrees, thus that will not work either. Right angles are exactly 90 degrees, so two right angles have to be supplementary.

Answer 2

Answer:

supplementary angle-180°

2 obtuse angle are more than 90° and there sum will be more than 180°

so, it can't be supplementary

1 question answer

2 question answer-

2 acute angles are less than 90° so there sum will be less than 180°

so, it can't be supplementary

3 question answer

right angle-90° and there sum will be-

90°+90°=180°

so, will be supplementary
