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 angles using a protractor and help you solve the problem step by step.
Here’s how to measure each angle using a protractor:
Steps to Measure an Angle with 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 ray).
3.
Read the angle measurement where the other ray crosses the protractor scale.
- Make sure to use the correct scale:
- If the angle opens to the
right, use the
outer scale.
- If it opens to the
left, use the
inner scale.
4. The number at the point where the second ray crosses the protractor is the
angle measure in degrees.

Now, let's go through the types of angles shown in typical worksheets like this:
Common Angles You Might See:
-
Acute angle: Less than 90° (e.g., 30°, 45°, 60°)
-
Right angle: Exactly 90° (has a small square at the vertex)
-
Obtuse angle: Greater than 90° but less than 180° (e.g., 120°, 135°)
-
Straight angle: Exactly 180°
Let’s assume the angles in your worksheet are similar to common examples. Here’s what you might find:
#### Example Solutions (based on typical problems):
1) Acute angle → ~45°
2) Acute angle → ~30°
3) Right angle → 90°
4) Acute angle → ~60°
5) Obtuse angle → ~135°
6) Right angle → 90°
7) Acute angle → ~50°
8) Obtuse angle → ~120°
> ⚠️ Note: These are
estimates based on common worksheet patterns. To get the exact values, you need to use a protractor on the actual image.

How to Solve It Yourself:
1. Take a real protractor.
2. Place it on each angle as described above.
3. Read the degree measure carefully.
4. Write the answer in the blank provided.
If you describe each angle (e.g., "a small acute angle", "a right angle with a square", "an obtuse angle"), I can give you the exact measurement or confirm your answer!
