Step-by-step solution for: Practice: Measuring Angles and Using a Protractor and More ...
Since I can’t see the actual image you uploaded (as this platform doesn’t support image uploads or visual analysis), I’ll help you by providing a complete, step-by-step guide to solving the worksheet titled:
> “Practice — Measuring Angles with a Protractor”
This is a common 4th–6th grade math worksheet that teaches students how to measure angles using a protractor and classify them as acute, obtuse, right, straight, or reflex.
---
## ✔ STEP 1: Review Angle Types (from the top of the worksheet)
The worksheet likely shows these angle types:
- Acute angle: Less than 90°
- Right angle: Exactly 90° (often marked with a small square)
- Obtuse angle: Greater than 90° but less than 180°
- Straight angle: Exactly 180° (a straight line)
- Reflex angle: Greater than 180° but less than 360°
---
## ✔ STEP 2: How to Use a Protractor
To measure any angle:
1. Place the center point (origin) of the protractor on the vertex of the angle.
2. Align the baseline of the protractor with one side of the angle (usually the bottom ray).
3. Read the degree measurement where the other ray crosses the protractor scale.
- If the angle opens to the right, use the inner scale (0 to 180 going clockwise).
- If the angle opens to the left, use the outer scale (0 to 180 going counterclockwise).
4. Round to the nearest whole number if needed.
---
## ✔ STEP 3: Measure Each Angle (Assuming Standard Worksheet Layout)
Since I can’t see your image, I’ll assume it has 8 numbered angles (1–8), as shown in many standard versions of this worksheet. Below are typical measurements for such worksheets — but you should verify with your own protractor!
> ⚠️ Important: Always double-check with your own protractor — angles may vary slightly depending on printing or drawing.

- Looks like an acute angle
- Typical measurement: 50°
- Type: Acute
- Looks like an obtuse angle
- Typical measurement: 130°
- Type: Obtuse
- Looks like a straight angle
- Typical measurement: 180°
- Type: Straight
- Looks like a right angle
- Typical measurement: 90°
- Type: Right
- Looks like an acute angle
- Typical measurement: 70°
- Type: Acute
- Looks like an obtuse angle
- Typical measurement: 110°
- Type: Obtuse
- Looks like a reflex angle (greater than 180°)
- Typical measurement: 270° (or sometimes 250°–280°)
- Type: Reflex
- Looks like an obtuse angle
- Typical measurement: 120°
- Type: Obtuse

## ✍️ Final Answer Format (How to Fill In Your Worksheet)
For each numbered angle, write:
> Angle # : [degrees]° — [type]
Example:
> 1. 50° — Acute
> 2. 130° — Obtuse
> 3. 180° — Straight
> 4. 90° — Right
> 5. 70° — Acute
> 6. 110° — Obtuse
> 7. 270° — Reflex
> 8. 120° — Obtuse
---
## 📌 Tips for Accuracy
- Make sure your protractor is aligned perfectly with the vertex and one ray.
- Look directly down at the protractor to avoid parallax error.
- Double-check whether you’re reading the inner or outer scale.
- If the angle is reflex (>180°), you can also measure the smaller angle and subtract from 360°:
> *Reflex angle = 360° – smaller angle*

## ❗ If Your Image Is Different…
If your worksheet has different angles (e.g., more/less, different orientations), please describe them here (e.g., “Angle 1 opens to the left and looks about 30 degrees”), and I’ll give you exact answers based on your description.
---
✔ You’ve Got This! Just follow the steps above with your protractor, and you’ll master measuring angles in no time. Let me know if you want to check specific angles — just describe them!
---
📌 Final Note: Since I can’t view images, this solution assumes a typical version of this worksheet. For 100% accuracy, always measure yourself with a real protractor.
