Q1 D of 22 Page 70

Let’s think and write:

Let’s write whether two obtuse angles are supplementary to each other.


No, obtuse angles are angles that measure greater than 90° and less than 180°

Supplementary angles are positive angles that add up to 180°.


If you add two obtuse angles that are each as small as possible, their sum will be more than 180°, so they can’t be supplementary.


Example - 91° + 91° = 182°
