Question

which angle number represents ∠lrk?

Explanation:

Step1: Recall angle - naming convention

An angle can be named using three points where the middle point is the vertex. For \( \angle LRK \), the vertex is \( R \).

Step2: Identify the angle at vertex \( R \)

Looking at the diagram, the angle with vertex \( R \) formed by rays \( RL \) and \( RK \) is labeled as \( \angle 1 \).

Answer:

\( \angle 1 \)
