Exercise 20 Page 463

What do you call two adjacent angles where the noncommon sides are opposite rays?

Yes.

Practice makes perfect

Let's highlight ∠ NKL and ∠ JKM in the diagram.

Since MN and JL intersect at Point K, and ∠ NKL and ∠ JKM are adjacent angles with noncommon sides that are opposite rays, we know these angles form a linear pair. Therefore, we can assume that the angles are supplementary.
