Question

which of the following describes an angle with a vertex at y?
a. ∠xzy
b. ∠xyz
c. ∠yzx
d. ∠zxy

Explanation:

Step1: Recall angle notation

In angle notation \( \angle ABC \), the middle letter is the vertex.

Step2: Analyze each option

• Option A: \( \angle XZY \) has vertex \( Z \).
• Option B: \( \angle XYZ \) has vertex \( Y \).
• Option C: \( \angle YZX \) has vertex \( Z \).
• Option D: \( \angle ZXY \) has vertex \( X \).

Answer:

B. \( \angle XYZ \)
