Since I can't view or access images directly, I can't see the specific angles in your worksheet. However, I can guide you on how to
measure angles using a protractor and help you solve this type of problem step by step.

🔧 How to Measure Angles with a Protractor:
1.
Place the center of the protractor (usually marked with a dot or cross)
on the vertex of the angle.
2.
Align one side of the angle with the zero line of the protractor.
3.
Read the angle measure where the other side of the angle crosses the protractor scale.
- Be sure to use the correct scale:
- If the angle opens to the
right, use the
outer scale.
- If it opens to the
left, use the
inner scale.
4.
Determine if the angle is acute (< 90°), right (= 90°), obtuse (> 90° but < 180°), or reflex (> 180°).

📝 Example Walkthrough (for practice):
Let’s say you have an angle that looks like this:
```

/________
```
- Place the protractor so the vertex is at the center.
- Align the bottom horizontal line with the 0° mark.
- The upper line might point to
60° on the protractor → So the angle is
60°.

✔ Tips for Accuracy:
- Make sure the protractor is flat and aligned.
- Use a ruler or straightedge if needed to extend lines.
- Double-check whether the angle is less than or greater than 90° before reading.

🔢 Common Angle Types:
| Type | Degree Range |
|------------|---------------------|
| Acute | 0° to 90° |
| Right | Exactly 90° |
| Obtuse | 90° to 180° |
| Straight | Exactly 180° |
| Reflex | Greater than 180° |

📌 What You Should Do Now:
1. Take your
protractor.
2. For each numbered angle (1–12), follow the steps above.
3. Write the measurement in the blank line below each diagram.
If you describe any of the angles (e.g., "angle 1 is a right angle", or "angle 5 looks like it's about 120 degrees"), I can help confirm or estimate the correct answer.
Would you like to describe one or more of the angles from the image? I’ll help you figure out their measures!
