It looks like you've uploaded a worksheet titled
"Vertex and Sides Formed by the Angle", which asks students to identify the
vertex and the
sides of various angles shown in diagrams. Since I can't view images directly, I’ll explain how to solve this type of problem based on typical geometry conventions.

🔍 Understanding the Task:
For each angle diagram:
-
Vertex: The common endpoint where two rays meet (the "corner" of the angle).
-
Sides: The two rays that form the angle (they extend from the vertex).
You are to label:
1. The
vertex (usually a point labeled with a letter).
2. The
sides (the two rays forming the angle, often named by their endpoints).
---
✔ General Steps to Solve:
1.
Locate the vertex:
- It's the point where the two lines or rays meet.
- Often labeled with a single letter (like A, B, C, etc.).
2.
Identify the sides:
- Each side is a ray starting at the vertex and going through another point.
- Name the sides using the vertex and the endpoint of each ray.
3.
Naming convention:
- For example, if the vertex is $ B $, and the rays go through points $ A $ and $ C $, then:
- Vertex: $ B $
- Sides: $ \overrightarrow{BA} $ and $ \overrightarrow{BC} $

📝 Example Walkthrough (Hypothetical):
Let’s assume one of the diagrams shows an angle with:
- Point $ A $ connected to $ B $, and
- Point $ B $ connected to $ C $,
- With $ B $ being the corner.
Then:
-
Vertex: $ B $
-
Sides: $ \overrightarrow{BA} $ and $ \overrightarrow{BC} $
> Note: The order matters — the vertex is always in the middle when naming the angle (e.g., $ \angle ABC $), but for sides, we name them as rays from the vertex.
---
🧩 Common Pitfalls:
- Don’t confuse the
vertex with other points on the rays.
- Make sure the
sides are named correctly as rays starting from the vertex.
- If there are multiple angles at a point, focus only on the one shown.

✔ How to Fill Out the Worksheet:
For each diagram, follow this format:
| Diagram | Vertex | Sides |
|--------|--------|-------|
| 1 | [Label] | $ \overrightarrow{AB}, \overrightarrow{AC} $ |
Repeat for all six diagrams.

🛠️ Tips:
- Look for labels on the points (A, B, C, etc.) — these help identify the vertex and sides.
- If no labels are given, assume the central point is the vertex.
- Always check the direction of the rays — they start at the vertex and go outward.

If you can describe one or more of the diagrams (e.g., “a triangle with points A, B, C and angle at B”), I can help you fill in the answers specifically.
