To solve the problem of measuring the angles using a protractor, we need to carefully observe each diagram and read the angle values from the protractor. Here's the step-by-step solution for each angle:
1)
- The angle is measured starting from the baseline (0°) on the left.
- The blue line extends to the 90° mark.
-
Answer: 90°
2)
- The angle is measured starting from the baseline (0°) on the left.
- The blue line extends to the 90° mark.
-
Answer: 90°
3)
- The angle is measured starting from the baseline (0°) on the left.
- The blue line extends to the 120° mark.
-
Answer: 120°
4)
- The angle is measured starting from the baseline (0°) on the left.
- The blue line extends to the 60° mark.
-
Answer: 60°
5)
- The angle is measured starting from the baseline (0°) on the left.
- The blue line extends to the 135° mark.
-
Answer: 135°
6)
- The angle is measured starting from the baseline (0°) on the left.
- The blue line extends to the 75° mark.
-
Answer: 75°
7)
- The angle is measured starting from the baseline (0°) on the left.
- The blue line extends to the 150° mark.
-
Answer: 150°
8)
- The angle is measured starting from the baseline (0°) on the left.
- The blue line extends to the 120° mark.
-
Answer: 120°
Final Answers:
1. 90°
2. 90°
3. 120°
4. 60°
5. 135°
6. 75°
7. 150°
8. 120°
Explanation:
- A protractor is a semicircular tool used to measure angles in degrees.
- To measure an angle:
1. Align the center of the protractor with the vertex of the angle.
2. Align one side of the angle with the baseline of the protractor (usually the 0° mark).
3. Read the angle where the other side of the angle intersects the protractor scale.
By following these steps for each diagram, we can accurately determine the angle measurements.
Final Answer Boxed:
\[
\boxed{90^\circ, 90^\circ, 120^\circ, 60^\circ, 135^\circ, 75^\circ, 150^\circ, 120^\circ}
\]
