Question

Sally and Suzie both agree that m∠A + m∠B = 180⁰.

Sally claims ∠A and ∠B are supplementary.

Suzie claims ∠A and ∠B are not supplementary because they are not adjacent.

Who is correct?

Answer 1

Answer: Sally is correct

Step-by-step explanation:

The angles do not need to be touching, or adjacent, for them to be supplementary. They simply need to add to 180 degrees.

We have 70+110 = 180, so that proves the angles are supplementary. They can be rearranged to glue together to form a straight angle.

If the angles were supplementary and adjacent, then we can consider them as a linear pair. This is possibly what Suzie might be thinking about.
