![### Identifying the Marked Angle
**Task:**
Name the marked angle in 2 different ways.
**Diagram Description:**
The diagram shows a quadrilateral named NMLK. The quadrilateral has one of its angles, specifically angle \( \angle M L K \), marked. This angle is shaded.
**Steps to Identify the Angle:**
1. **Using Three Points Notation:**
- The angle can be named based on the three points that form it. The middle letter must be the vertex of the angle.
- Therefore, the marked angle at vertex L can be named as \( \angle M L K \) or \( \angle K L M \).
2. **Using Vertex Notation:**
- If each vertex is unique to the angle, the angle can also simply be named by its vertex.
- Hence, the marked angle can be named as \( \angle L \).
**Input Fields:**
- Two input boxes are provided for the user to enter the names of the angle based on the methods above.
Example Answers:
- **First box:** \( \angle M L K \)
- **Second box:** \( \angle K L M \)
**Interactive Elements:**
- After entering the angle names, the user can click the "Submit Answer" button to validate their responses.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F5ddc3929-1beb-4dd6-a443-39e9bbd8ad94%2F498fac1f-5a39-4d9e-a092-80bdd09971d9%2Feg7v82k_processed.jpeg&w=3840&q=75)
