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
solve the problem and
classify angles based on the instructions provided.

🔍 Understanding the Task
The worksheet asks you to:
1.
Measure each angle using a protractor.
2.
Classify each angle as
acute,
obtuse, or
right.
---
✔ Definitions of Angle Types:
-
Acute angle: Less than 90°
-
Right angle: Exactly 90° (looks like a square corner)
-
Obtuse angle: Greater than 90° but less than 180°
---
📏 How to Measure an Angle with a Protractor:
1. Place the
center point of the protractor at the
vertex of the angle.
2. Align one side of the angle with the
zero line of the protractor.
3. Read the degree measure where the other side crosses the protractor scale.
4. Make sure you're reading the correct scale (inner or outer) depending on which direction the angle opens.

🧩 Step-by-Step Classification:
Let’s assume you have nine angles labeled 1 through 9. Here's how to approach each:
#### Example:
If angle #1 looks like it's more than 90°, say around 120° →
Obtuse
If angle #5 looks like a perfect L-shape →
Right angle
If angle #9 is very narrow, like 30° →
Acute

🔎 Common Patterns in Such Problems:
Here are typical angle types found in these worksheets:
| Angle Type | Approximate Degree | Shape |
|------------|--------------------|-------|
| Acute | 30°, 45°, 60° | Narrow "V" shape |
| Right | 90° | Square corner |
| Obtuse | 100°, 120°, 135° | Wide "V" shape |
---
✔ Final Answer Format (Example):
After measuring each angle:
1.
120° →
Obtuse
2.
100° →
Obtuse
3.
45° →
Acute
4.
170° →
Obtuse
5.
90° →
Right
6.
135° →
Obtuse
7.
90° →
Right
8.
30° →
Acute
9.
20° →
Acute

🛠 Tips:
- Double-check that the protractor is aligned properly.
- Use a ruler to extend lines if needed for better measurement.
- Look for visual clues: right angles often have a small
square symbol.

Would you like me to help you classify the angles if you describe them (e.g., “angle 1 looks wide, almost flat”) or provide the measurements?
