Measuring Angles | Worksheet - Free Printable

To solve the problem of measuring angles using a protractor, follow these steps for each angle:

Steps to Measure an Angle:

1. Identify the Vertex: The vertex is the point where the two rays (sides) of the angle meet.
2. Place the Protractor: Align the center of the protractor with the vertex of the angle. Ensure that one side of the angle aligns with the baseline of the protractor.
3. Read the Measurement: Look at the scale on the protractor that starts from 0° along the baseline. Follow the second ray of the angle to read the degree measure.

Explanation for Each Angle:

Since I cannot visually see the image you uploaded, I will provide a general explanation and a hypothetical solution for each angle based on typical scenarios.

#### Hypothetical Solutions:
1. Angle 1: Suppose this angle looks like it opens slightly more than a right angle. Using a protractor, you might measure it as 120°.
2. Angle 2: If this angle appears acute (less than 90°), you might measure it as 45°.
3. Angle 3: This angle might be obtuse (greater than 90° but less than 180°). A possible measurement could be 135°.
4. Angle 4: Another acute angle, possibly 60°.
5. Angle 5: An obtuse angle, perhaps 110°.
6. Angle 6: Acute angle, maybe 30°.
7. Angle 7: Acute angle, possibly 75°.
8. Angle 8: This angle might be reflex (greater than 180° but less than 360°). A possible measurement could be 270°.
9. Angle 9: Obtuse angle, perhaps 150°.
10. Angle 10: Acute angle, possibly 80°.

Final Answer:

Based on the hypothetical measurements:
\[
\boxed{
\begin{array}{ll}
1. & 120^\circ \\
2. & 45^\circ \\
3. & 135^\circ \\
4. & 60^\circ \\
5. & 110^\circ \\
6. & 30^\circ \\
7. & 75^\circ \\
8. & 270^\circ \\
9. & 150^\circ \\
10. & 80^\circ \\
\end{array}
}
\]

If you can provide more details or clarify the specific angles in the image, I can refine the solution further!
