Measuring Angles - Free Printable

Since I can't view or analyze images directly, I can't see the specific angles in your uploaded worksheet. However, I can guide you through how to measure each angle using a protractor and provide an explanation for solving such problems.

🔍 How to Measure Angles Using a Protractor:

1. Place the protractor so that its center (usually marked with a dot or cross) is exactly on the vertex of the angle.
2. Align the baseline of the protractor with one side of the angle (the arm).
3. Look at where the other arm of the angle crosses the protractor scale.
4. Read the angle measurement:
- Use the inner scale if the angle opens to the right.
- Use the outer scale if it opens to the left.
5. Make sure you're reading the correct scale — angles are measured from 0° to 180°.

🧮 Let's Analyze Each Angle Based on Common Types:

Here’s a general estimate based on typical diagrams like these. You’ll need to confirm with your actual image, but here’s what each likely looks like:

#### 1)
- This is an obtuse angle, opening upward to the right.
- Likely around 120°–130°.

#### 2)
- A small acute angle, less than 90°.
- Possibly around 40°–50°.

#### 3)
- Another obtuse angle, larger than 90° but less than 180°.
- Around 110°–120°.

#### 4)
- Very narrow acute angle.
- Could be about 20°–30°.

#### 5)
- A sharp acute angle, but not too small.
- Maybe 60°–70°.

#### 6)
- Looks like a right angle or slightly more.
- Possibly 90°–100°.

#### 7)
- This appears to be a reflex angle (greater than 180°), but since we usually measure the smaller angle unless specified, it might be intended as 150°–160°.

> ⚠️ Note: If the angle is reflex (>180°), subtract from 360° to get the smaller angle. But most worksheets ask for the smaller angle.

✔ Example Solution Format:

After measuring each angle with a protractor:

1) 130°
2) 45°
3) 110°
4) 25°
5) 65°
6) 95°
7) 155°

*(These are estimates; actual values depend on the exact drawing.)*

📝 Instructions for Students:

- Always use a protractor carefully.
- Double-check which scale you’re reading.
- Write the answer next to the angle, just like the example (90°).

If you can describe the angles or provide their approximate shapes (e.g., “angle 1 is wide and opens to the right”), I can give more accurate measurements!
