Since I can't view or access images directly, I can't see the specific angles in your uploaded image. However, I can help you solve
Angle Classification 2 if you describe the angles or list them.
But based on the title and typical structure of such worksheets, here's how to classify angles:
🔺 Angle Classification:
-
Acute angle: Less than 90° (e.g., 45°)
-
Right angle: Exactly 90° (forms a square corner)
-
Obtuse angle: Greater than 90° but less than 180° (e.g., 120°)
-
Straight angle: Exactly 180° (forms a straight line)
---
✔ How to Solve:
For each angle shown in the worksheet:
1. Look at the shape of the angle.
2. Compare it to a right angle (like the corner of a square).
- If it's
smaller, it’s
acute.
- If it’s
equal, it’s
right.
- If it’s
larger but less than a straight line, it’s
obtuse.
- If it’s a
straight line, it’s
straight.

📝 Example:
Let’s say one angle looks like this:
```
/
/
/
/
/_____
```
This is
less than 90°, so it’s
acute.
Another angle:
```
______
/ \
/ \
__________
```
That’s more than 90°, so
obtuse.
A square corner:
```
|_____
| |
|_____|
```
That’s
right.
And a straight line:
```
-----------
```
That’s
straight.

🛠️ Tips:
- Use a protractor for accuracy if needed.
- Look for small
square symbols — they indicate
right angles.
- Angles that open wide but not fully flat are
obtuse.
- Very narrow openings are
acute.

If you can describe the angles in the image (e.g., "the first one looks like a sharp corner", "the third one has a square box in the corner"), I can tell you how to classify each one!
Just reply with the descriptions or list the shapes, and I’ll help you fill out the worksheet!
