It looks like you've uploaded a worksheet titled
"Measuring Angles - 5° Increments", which asks students to measure various angles using a protractor and record their answers in degrees. Since I can't view images directly, I'll explain how to solve this type of problem and guide you through the steps.

🔍 Understanding the Task
The worksheet contains six diagrams (labeled 1–6), each showing an angle formed by two rays with a vertex labeled (e.g., ∠ABC). The goal is:
1. Use a
protractor to measure each angle.
2. Write the measurement in degrees (in 5° increments).
3. Round to the nearest 5° if necessary.

✔ How to Measure an Angle Using a Protractor
Follow these steps for each angle:
1.
Place the protractor so that:
- The center point (usually marked with a dot or cross) is on the
vertex of the angle.
- One ray of the angle lines up with the
0° mark on the protractor.
2.
Read the degree measure where the other ray crosses the protractor scale.
- Make sure you're reading from the correct scale (inner or outer) depending on which direction the angle opens.
3.
Record the answer in the space provided, ensuring it's in
5° increments (e.g., 45°, 50°, 75°, etc.).

📝 Example Walkthrough
Let’s assume one of the angles (say, #1) looks like this:
- Vertex at point B
- Ray BA goes left
- Ray BC goes down-right
- The angle appears to be
about 45°
Then you would write:
m∠ABC = 45°
If the angle is slightly more than 45° but less than 50°, round to the nearest 5° — so
50°.

⚠️ Tips
- Always double-check which scale you’re using (clockwise vs counterclockwise).
- Ensure the protractor is aligned properly — misalignment leads to incorrect measurements.
- For reflex angles (greater than 180°), subtract from 360° or use the outer scale.

🧮 Sample Answers (Hypothetical)
Since I can’t see your image, here are
example answers based on typical problems like this:
| Problem | Measurement |
|--------|-------------|
| 1 | m∠ABC = 45° |
| 2 | m∠DEF = 120° |
| 3 | m∠GHI = 90° |
| 4 | m∠JKL = 150° |
| 5 | m∠MNO = 60° |
| 6 | m∠PQR = 135° |
> These are just examples. Your actual answers will depend on the specific angles shown in your image.

💡 Final Advice
To get accurate results:
- Use a clear, transparent protractor.
- Align carefully.
- Read the scale carefully.
If you can describe the angles or provide text versions of the diagrams, I can help give exact solutions!
