Here is the diagram based on the provided angle relationships:

• <1 is adjacent to <2.
• <2 and <3 form a linear pair.
• <2 and <4 are vertical angles.
• <4 and <5 are complementary angles.

Would you like further details or explanations about any of the relationships between the angles?

Here are 5 questions to deepen your understanding:

1. What is the definition of vertical angles?
2. How do you calculate complementary and supplementary angles?
3. How are linear pairs used in geometry?
4. What are adjacent angles, and how are they related to other angle types?
5. Can two vertical angles ever be complementary?

Tip: In geometry, vertical angles are always congruent, meaning they have equal measures.
