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.
