9. These are examples of adjacent angles.

10. These angles are NOT adjacent.
Explain why each example is NOT adjacent. You may start as:
Example 1 is not adjacent angles because __________
Example 2 is not adjacent angles because __________
Example 3 is not adjacent angles because _________________

11. Vertical angles: two lines intersect and they make vertical angles (opposite). Vertical angles are congruent (same measure).

12. Congruent Angles
Congruent angles means angles have the same measure.

13. Adjacent Angles:
∡𝑉𝑊𝑋 𝑎𝑛𝑑 ∡𝑉𝑊𝑍
Vertical Angles:
∡𝑉𝑊𝑋 and ∡𝑍𝑊𝑌
