Show Answer Key & Explanations Step-by-step solution for: 4th grade geometry angle classification 2 | Geometry worksheets ...
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!
