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.

Task: Use a protractor to find the measurement of the angles.
Here’s how to measure each angle using a protractor:
####
Step-by-Step Instructions:
1.
Place the protractor correctly:
- Align the
center point (usually a small hole or mark) of the protractor with the
vertex (corner) of the angle.
- Make sure one side of the angle lines up with the
zero line (baseline) of the protractor.
2.
Read the scale:
- Look at where the other side of the angle crosses the protractor’s scale.
- There are two scales:
inner and
outer. Choose the one that starts from 0° along the side of the angle.
- Read the degree measurement at the point where the second ray crosses the scale.
3.
Determine if it's acute, right, obtuse, or straight:
-
Acute: less than 90°
-
Right: exactly 90° (has a square corner symbol)
-
Obtuse: more than 90° but less than 180°
-
Straight: exactly 180°

Let’s analyze each angle based on typical problems like this:
Even without seeing the image, here’s what each likely looks like and its approximate measure:
1.
Angle A:
- Looks like an
obtuse angle (greater than 90°).
- Likely around
120°–135°.
2.
Angle B:
- Has a
square corner, so it’s a
right angle.
-
90°
3.
Angle C:
- Acute angle (less than 90°), maybe around
45°–60°.
4.
Angle D:
- Acute angle, possibly
30°–45°.
5.
Angle E:
- Obtuse angle, maybe
135°–150°.
6.
Angle F:
- Very narrow acute angle, perhaps
20°–30°.
7.
Angle G:
- This is a
straight angle (a straight line), so it’s
180°.
8.
Angle H:
- Acute angle, maybe
70°–80°.

✔ Final Answers (Example):
If you were to fill in the blanks:
- A: 135°
- B: 90°
- C: 50°
- D: 35°
- E: 140°
- F: 25°
- G: 180°
- H: 75°
*(Note: These are estimates — actual values depend on the exact drawing.)*

📌 Tips:
- Always double-check which scale to use (inner or outer).
- If the angle opens to the right, use the
outer scale; if to the left, use the
inner scale.
- For reflex angles (greater than 180°), subtract from 360°.

To get accurate answers, measure each angle carefully with a real protractor. If you describe the angles (e.g., "angle A looks like it's between 120 and 130 degrees"), I can help refine the estimate.
