The image shows a diagram with angles labeled around the intersection of two lines. The question asks for an angle that is adjacent to ∠1. In the diagram, ∠1 is located at the top-right quadrant of the intersection of two lines, and the angle adjacent to it would be the angle directly next to it, sharing a common side.

From the diagram, the angle adjacent to ∠1 is ∠4 because it shares a common vertex and side with ∠1.

2. How do adjacent angles differ from vertical angles?
3. Can adjacent angles be supplementary or complementary?
4. How are angles formed at the intersection of two lines classified?
5. What is the sum of adjacent angles around a point?

Tip: Adjacent angles always share a common vertex and side but do not overlap.
