Since I can't view or access images directly, I can't see the specific angles in your uploaded worksheet. However, I can guide you through how to solve this type of problem and explain the process step by step.

How to Measure Angles Using a Protractor
1.
Place the Protractor Correctly:
- Align the center point (usually marked with a cross or dot) of the protractor on the
vertex of the angle.
- Make sure one side of the angle lines up with the
0-degree line on the protractor.
2.
Read the Measurement:
- Look at where the other side of the angle crosses the protractor’s scale.
- 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.
- Read the degree measurement at that point.
3.
Determine if It's Acute, Right, or Obtuse:
-
Acute: Less than 90°
-
Right: Exactly 90°
-
Obtuse: Greater than 90° but less than 180°
-
Straight: Exactly 180°

Step-by-Step Example (Hypothetical):
Let’s say one of the angles looks like this:
```
/
/
/
/
/
/________
```
- Place the protractor so the vertex is at the center.
- One ray aligns with 0° on the right.
- The other ray points to about 45° on the outer scale.
- So, the angle is
45 degrees.

Common Angle Types You Might See:
| Angle Type | Degree Range | Example |
|-----------|--------------|--------|
| Acute | < 90° | 30°, 60° |
| Right | = 90° | Perfect corner |
| Obtuse | > 90° and < 180° | 120°, 150° |
| Straight | = 180° | A straight line |

Tips for Accuracy:
- Double-check alignment.
- Make sure the protractor is flat on the paper.
- Read the scale carefully—don’t confuse inner and outer scales.

If you describe the angles (e.g., "angle 1 is a small acute angle opening to the right"), I can help estimate or confirm the measurements. Alternatively, if you provide the actual measurements after using a protractor, I can verify them!
